Is blowing air against the back of your neck while you sit at a bar, (as they walk to the bathroom and don’t look back), a thing for women? Is that a deliberate signal of interest in a man? Maybe this belongs in the EILI5 sub

I should mention, specifically, I was at a bar waiting for friends, looking at my phone, and I noticed a very distinct blow of human breath on the back of my neck. I turned and saw a cute girl had just passed and headed to the bathroom. I’m embarrassed to ask because I’m either imagining something or I missed a great opportunity, I’m quite dense with female signals
