I am normally with a wing or engage 1-set or group sets. However in a couple days I'm going to be sarging alone and if I come across a target that's in a 2-set how do I close? I know how to open and get the targets friend to be comfortable with me but I feel it would awkward to try K-close with her friend around, and if you #-close won't the other girl feel left out when you only ask for the targets #?
