I really would like to know how I can "touch" someone when I'm attempting to open with someone and get some rapport going. I dont have many issues actually talking, but the physical contact is such an important element from what I've seen and heard; and to me touching someone I've known for a few minutes seems insane. Please elabortate instead of "just do it". Everyone's different i know but what are some of the best ways to do this to clearly show my intent? I'm in my early 20s and am in the states for cultural relevancy
