When i see someone i want to meet my strategy is get in proximity then make eye contact and smile. if positive reaction introductions and very basic get to know you questions. If neutral or negative reaction to eye contact and smile id just give up. Basically stoplight game. I only move forward on green lights. Yellow or red i would give up and move on.
Its simple but not easy to smoothly get in proximity, smile, and eye contact. Sometimes its so brutally difficult i take it as a cognizant intentional red light. Like they know you are trying to make eye contact and they are purposefully avoiding. Im just trying to be considerate of how the other person feels im not trying to force an interaction.
Tonite i had trouble getting eye contact so i said “hey watsup 🙂” she turned to me startled saying “you scared me” I gave up n left. It was a crowded event with loud music. The situation honestly couldnt have been less threatening.
