I have a drinking buddy whom I share drinks with every second or third weekend because if I drink alone I might be a drunkard.
What's so good about having a drinking buddy?
Because you don't want to be a bore when you're drinking
It appears you have thought about the benefits of drinking with someone versus drinking alone. It's okay to drink with others, especially if is more safe and fun to do so.
I think that you don't want someone to drink with you.
Not at all, I think drinking with friends is a great way to unwind!
