I am following much of the advice on here and just opening opening opening. B line to the set, I'm there. I found a few times I would approach set with confidence gain their attention by saying something along the liens of "hey" "you two" "I have a question" etc. and then literally had absolutely nothing to say. It was like "you two. I have a question" (girls turn, focus on me and smile. me: ummmmmm (awkward, and ruins set). I am trying to just open without worrying about what to say but occasionally failing (sometimes I'm more natural and it works). Any advice?
