I am wondering if the basic physical escalation we start with(starting with tap on shoulder, putting hand on shoulder, arm) should appear intentional or should appear that we do that subconsciously without knowing it because its a habit. I think if it looks intentional, then it would send clearer signal that we are interested. Moreover, I have seen few times I miss because of distance or very few times hands don't land that perfectly as I thought.
I feel that higher level kino mentioned in
