Ok, double dating is different obviously then regular dating. It's going to be my brother, his g/f of about 2 months, me and a girl(who is friends with his g/f) who i barely know. We are going mini golf...i posted this in the regular section but since we are all 17, thought i would post it here. How should I approach this? Any special things to do? Any specific things to do since its a double?
