I'm going to ask a recovering alcoholic why they aren't drinking
Are you kidding, why do you have to ask something that sensitive?
I want to be friends with someone who's like me
You shouldn't remind a recovering addict of their addiction. They might relapse if it feels like you are encouraging them and undo all of their progress.
That's so boring. How about I ask them with one drink.
Please don't, it's not a good idea to try to be a bad influence to someone that is recovering like you. Don't you want the both of you to succeed, and see better days? How about just going out to see a movie or something and talk about it then?
