Your logic is great stuff!
You are incorrect that everyone goes to bars and parties. Nope. Not true! I said the same thing when I was drinking. However, I thought that way because everyone that I knew drank. That is a very small minority.
Normal people do not drink. If they do it may be a glass of wine, or a mixed drink, when they go out to eat. My wife does not drink. The people in her life do not drink.
