Whether you still can't get through a weekend without going clubbing or you haven't stepped foot inside a club for months, one thing's for sure - the experience definitely changes when you're somewhere around the early 20s age.
You'll go out with the best intentions of feeling like you're 18 again but at some point during the night, no matter how much you've had to drink, you'll realise that things aren't what they used to be. For a start, alcopops aren't as alarmingly cheap as they were a few years ago - although that's probably a good thing.
There was a time when you had to beg with the bouncers to let you in when you let your sister borrow your ID. "I'm 19, I promise," you'd say as you tried to use a debit card as proof of age. Now, you're offended when the don't even ask for any form of identification. Way to make a girl feel old...
2. Drinks get spilled all over you.
Yes, this has always happened but the difference is a) you notice it and b) you get very annoyed when the same guy tips his vodka and coke down your new Topshop dress for a third time. (Yes, you've been counting.)
3. You refuse to share a toilet cubicle.
No matter how desperate you are for the loo, there's no chance you're cramming in with two of your friends anymore. You'll just wait in the queue and realise how unflattering the lighting is in nightclub toilets.
4. You spend more time in the smoking area outside than you do on the dance floor.
There's only so much dancing to cheesy pop songs a girl can do. Plus, everyone seems to be slightly cooler (and probably older) in the smoking section. Outside is where you want to be.
5. You don't know the songs.
You know the classics better than anyone, but the new stuff? Er, it's kind of familiar but you don't know who it's by or what the song is called. And yet the teenagers next to you are singing along to all the words. Does this mean you're old? No. You just don't spend as much quality time with MTV Hits as you used to.
