That was a little bit tongue in cheek. Look at my username. But I'll humor the question.
I don't like to drink at home because I quickly go from being an affable drunk to a hardcore alcoholic. I like people watching. The noise of a bar can drown out my thoughts so I'm not living in my own head.
Why do you think you know what's best for anyone else? Instead of deciding people are weird for being different, maybe you could examine yourself and find out why you're a judgemental ass when there's no way you could have all the information on someone else's life.
No one asked you to be. I humored your question. It's almost like you didn't really want an answer, you just wanted to be condescending.
Sounds like you've got some things to shove up your ass. Good luck in there.
