I have hair that grows out of my ears now. :sigh: I'm getting old.

When they let me into bars.

I'm not old. I may be in college, but I will always be a high school freshman at heart.

When I turned down lawn seats for a concert.

Are you insane?!
Well, I am not old. So I cant realise I am old if I'm not. Right?

gray hair, I was born in another millennium then the one we're in now, I'm the only one of my friends who isn't A) married B) pregnant/has kids C) or both. I think the last one is the clincher though, oh and the 'you wanted to change the world, well you now have used up a quarter of your life and have nothing to show for it' reason for my one and only panic attack right there actually

Age 7. I've spent my entire life waiting to be 30 so my personality will finally match my age.

When my friends kid said "who is Michael Jackson"

The semester when none of my students said they had ever made a mixtape for someone they liked.

Or maybe romance is just dead to this generation?

EDIT: I should qualify that. I'm an adjunct professor at a university

Ditto. Also suddenly occurred to me that I probably should have had more fun with my childhood when I could have gotten away with things like throwing worms at people and playing on a Gameboy in public without being judged.

MIXED CDS!!

Wait, YOU MAKE YOUR OWN MUSIC AND SEND IT AS AN MP3 ON MSN MESSENGER!!!

My brother, he is 29 now, did actually make his own song for his girlfriend, its 3 years ago, I think. And not "own song" as in ripping random songs, and make your own mp3, he actually wrote the song, and played it on guitar himself.

The only time playing guitar is acceptable is when it leads to potentially large chances of sex.

EDIT: I never realized anything, since I'm not old yet! I'm still studying.

When I realized I'd been working a 9-5 office job for a year now, and I am not even close to realizing any of the dreams I had for my adult life.

That gentlemen is what professionals refer to as a quarter life crisis. I believe ABC tried to make a sh*tty tv show about it.

Susan Arendt:
Two key moments let me know I was an adult (not old, per se, but an actual grownup):

1. When I turned down lawn seats for a concert.

2. When I looked at a major appliance and went "Oooo....."

Lawn seats at concerts is for cool people of all ages. Standing up and jumping up and down is for pillocks.

But I cannot refute the part about apliances. ^^

I realized I was old when I went to a local convenience store and their computers were off line. The clerk (a high school graduate) could not figure out how to make simple change without a computer!

Back in my day we learned basic math with that there diploma-thingy ;)

When staying out drinking until 2am became really, really hard, and not particularly appealing.

mintsauce has definately hit one of the true telling points right on the nose.

I'll add, when I realized that I cannot do my job well on less than 7 hours of sleep. Goodbye 2 a.m. bedtimes.

2am? Teetotaller :D

the moment that the battle "videogames vs. sleep" was lost for the videogames... like a year ago

Susan Arendt:

2. When I looked at a major appliance and went "Oooo....."

I've been doing that as long as I can remember...

Martha Stewart is one of my heroes! >.<

I'm not actually that old but I've had that weird "geez I'm ancient" feeling when I realised I was beyond the age I could pick up a sport and still - if I worked for it - reach pro level. Oh, and when I noticed some of the younger sportsmen and women are younger than me.

Yeah, just not going to sit on the ground for three hours. If I don't get at least a bench, I ain't goin'.

Oh, and also, when parking availability became a concern. That's a sign of adulthood, right there.

Ain't that the truth, I don't go anywhere anymore without knowing exactly how I can get home. My activities are dictated by how much I plan on drinking and the proximity to a transit station.

The sad thing is, I know realize how hard it is to go out drinking/partying anymore, especially when I have to clean my house the next day and do laundry so I have clothes during the week.

Being a grown up sucks.

I never liked concerts. Two of the four times I've gone to one, I wound up with bird nastiness on me. ;-;

And you know you're old when you have someone called, "The Nastalgia Critic" reciting your childhood, and some things you never knew.

Also, you know you're old when you try to argue that SMBS things are a little too much for a site claiming to be PG-13.

When everyone started calling me sir when I go to shops.

When I started getting hang overs.

When I started to go to bed at a reasonable time.

At the minute I need a new phone and a new vacum cleaner, and some how the vacuum cleaner is in the lead.

However I did a lifetime of drink and drugs between the ages of 14 and 19 so Im happy with a simple life right now

Sulla pitied his advancing years by the fact that all his enemies gradually became younger. Same here, without all the enemies part of course.

When I had to explain what the term "narc" means to a bunch of teenagers.

When I turned 20, and having no real age goals anymore. What I mean is that when your 12 years old your looking forward to being a teenage.
When 15, in 1 more year you can get your liscence.
17; soon you can go to quebec and get smashed (legally, most people are I swear are 15 anyways) and vote and whatnot
18: one more year you can legally drink in Ontario
19..... well your pretty much out of goals other than turning 21 and doing a road trip of the US.

EDIT: also forgot to add, when everyone younger than you, simply annoys the hell out of you for the shear stupidity of their actions and ideas.

whenever someone reiterates that the first game they ever played was Sonic The Hedgehog or any game made after that.
