Ahh, you need to get experience to beat those problems.
When growing up, getting old enough to drink legally, you learn many key skills. After many friday nights coming home pissed as a fart and not wanting to look too wasted to the old parents, you soon learn to act pretty sober while barely being able to retain control of your bladder.
This could turn into a debate about drinking but people shouldn't dismiss alcohol as a "It's sad people have to drink to have fun" drink. Yes, it's good to be able to have fun without alcohol, but it's all about inhibitions. Inhibitions make life boring, and although being a fun person means you're able to shrug off most of those inhibitions and have fun, alcohol lets you shrug off a hell of a lot more. It gives you dutch courage with the ladies - it lets you tell jokes you wouldn't normally tell, and it makes jokes that are normally pretty average seem farkin funny! hehe.
I too think its sad when people think drinking is the only thing they can do on a friday/saturday night for fun, but don't dismiss the booze!!!
There's a reason why so many people drink, and there's a reason why the nights with drinking always throw up more stories and more laughs - cos without the inhibitions, people are generally a lot more fun. ...... especially quiet people who are normally reclusive ... gets them chatting and gets the night swinging for them too.
*Raises a glass to booze!*
Insiiiiiiiiiiiiiiiiiiiiiiiide!
