In line to park at a rock concert the people next to you which look to be just your age are in a Crown Victoria. (I was still trying to get over that one when at the next concert I went to when I was CARDED for a beer. 
I’m better now.)
…you see Satan’s thread about Lynryd Skynyrd and think “Say, didn’t they all die in a plane crash back when I was fifteen? I remember making jokes about it in bio lab…”
And I have to echo TVeb’s irritation with baby right-wingers who say Clinton’s wick-lickin makes him a worse person than Tricky Dick.
…when you still use DOS to accomplish some mundane Windows tasks.
Uke: I may be a baby right-winger, but even I’m not stupid enough to believe that Clinton is as scummy as Nixon was.
Anyways, for aging:
You know you’re getting old when you look forward to male pattern baldness because it might start taking out your gray hairs.
Or, you’re driving down Lake Shore Boulevard, being home in Chicago for the first time in five years, you find a GREAT radio station, you are the coolest, hippest babe in sight … and then they announce that it is, “Retro Flashback Weekend! Flash back to the 80s …”
I nearly drove off the road.
According to Purplebear you know your getting old when your BABY goes off to college.
When you find yourself singing along to the music they play while shopping for groceries. Or when your baby grows taller than you. Or when you realize you’ve been in the same business for twenty years…
Sniffles WEELLLLL? So what? 
He’s only 17!
Like you’re any better my dear? 
You know you’re getting old when you check out a thread, and realize that you can relate to almost all of the posts to it. :eek:
And, puglvr, I love your definition of Gregg shorthand! 
Would you believe I still use some of it? :rolleyes:
You know you’re old when…
…you forget you posted this thread.
When you see these 15-year veteran wrestlers and realize that they are still younger than you.
When you long for the day that Turbo Pascal returns to business use. Its the only high-level language that was nearly as fast as assembler.
[hijack]My daughter is 19 months old. She thinks that “up” is pronounced “up-uh” because every time I pick her up I say, “UP-ugh!” [/hijack]
…when your pubic hair turns grey.
. . . even the largest tampons migrate.
A teen age girl talk to me leaving the grocery store. I think she liked my cool shirt. She didn’t use a single full sentence, and she might as well have been speaking mongolian. I only remember the last phrase, something like “You go man or dude”. Help!
When you walk into a toy store to buy bubble mix and the salespeople eye you suspiciously 
…everything either dries up or leaks.
…the people who used to call you “weird” now refer to you as “eccentric.”
When you first hear “excuse me ma’am”.
I first heard this from a 19 year old boy who after having had to run 3 red light to do it, T-boned my car and ran over to me and said-- Excuse me Ma’am, I had the green light, perhaps you couldn’t see it.
I was 32. My car was totaled; I was bloodied and broken; I had fractures, bruises, whiplash, etc., AND I had been called the M word.
