Or husband, NTTAWWT.
I had a guy yell that one time when he was passing me, I was all the way on the right side, and once he got by me he stopped, turned around, and yelled at me for not "acknowledging" him. He was upset that I didn't say something back, or give him a wave, or something. That was a new one for me. Guessing if he's married, his wife hates him.
