Just found this and thought I needed to share it... it's in German originally, so excuse my poor (and probably full of mistakes) translation...

You know you're all grown up when...

1. All your plants are alive and you can't smoke one of them.
2. Sex in a single bed is unbearable.
3. There's more food than drinks in the fridge.
4. You get up at 6am instead of going to bed at that time.
5. Your favourite song is being played in the lift.
6. You call the police cause 'those teenagers next door' got their music tuned up WAY too loud.
7. Your dog gets quality dog food instead of the leftovers.
8. You buy aspirin in the pharmacy, not condoms.
9. A bottle of whine that comes by 4 Euro isn't 'Pretty good stuff' anymore .
10. You spend 90% of your time in front of a PC ... to actually WORK.
11. You don't start drinking at home before actually going to out to save the money.
12. You frantically search this list for a number that does NOT apply to you!
