Is AUTHOR wrong in the post ? POST : I have been invited to a birthday party for tonight.   
For several reasons (party location, personnal health choices, ...) I do not intend to drink alcohol tonight.  We've all been asked to bring a bottle in so we can have fun. As I do not intend to drink alcohol from anyone, does it seems "unfair" if I don't bring alcohol in as long as I do not have a dingle drop of alcohol from other people?  
I'd still bring some softs in of course but nothing else. AITA for considering it?
