This gentleman works across the hall from my office, in his 40s, not married. i feel he may be somewhat aware as I notice him in a way where he can sense it, he began to smile at me in the morning, I then drew back, he started to run into me but I was far too shy so I acted indifferent, Christmas break came and went and he no longer smiles at me. what do I do? I was thinking put a note on his car asking his name, see if he guesses who it's from. Any ideas?
