Drinking

Isn't it funny or maybe sad is the right word that people need to drink at parties to have fun?

I noticed it a lot of times in my life that people that normally seem to have so much fun as they have there Alcohol beverage but then when they need to drive and because of that don't drive the fun seem to be gone.

In my case I don't drink so i don't really get that why does the couple of drinks you have make so much of a difference. Are you really so closed that you need the drink to loosen up?
