I go for a run every Saturday morning and I quite regularly see a man who is also running. A few weeks ago he was wearing shorts and I admit I probably did look him up and down when we passed each other and I think he saw this. I then gave him a little smile, which most people do when they pass each other. When we passed each other a second time I think he wiped his sweat off and adjusted himself just before we got to each other.
Fast forward a couple of weeks and when I saw him next I looked down as I was a bit embarrassed to be honest but just as we passed, I looked up at him and he was smiling at me.
Anyway, he is good looking and for some reason I am really drawn to him. Obviously I know nothing about him or his relationship status but AIBU to try and flirt, or say something to him, try and attract his attention etc? What should I do?
