There's not really anything in particular that causes me to walk-up to someone. Sometimes I recognize a name from an event, sometimes I spy an emote that I just -have- to go interact after, sometimes I pick a face at random in a crowd and see what happens. Roka is normally pretty friendly so is easy for me to drop her in on someone (she's been a little grumpy the past week due to story reasons).
I -love- when people walk-up to me as well. I might have a short panic moment, but I jump on in happily afterward.
