Are you drunk right now because I thought it was pretty clear we were talking about drinking alchohol.
Alcohol is nice because it helps relax you and get you in a good mood, so you can have fun with your friends.
You don't need alcohol to have fun with friends, but it's a different sort of fun when you've had a drink.
And that type of fun changes depending on how much you've been drinking.
I'm the kind of guy who likes to have 2-3 pints of cider or beer in a night, and it leaves me more mellow and relaxed, but fully aware of my surroundings and actions.
There have been a few nights out that would've been unbearable without a few units in my system.
And, like a normal person, I'm perfectly capable of deciding when and how much I drink. I can even turn down drinks offered to me when I don't want to drink.
Just because you're terrified that you can't handle a drink, or because others do abuse alcohol, doesn't mean people are incapable of drinking sensibly, or that it is inherintly dangerous.
Also, a glass of red wine then and now is good for your heart.
