I know that I sound like I'm about 13, but I haven't interacted with hardly anyone new in about a year, plus I've not dated in over 10 years (recently divorced).
I was on a video call with a man whom I've been working with recently. We are a similar age. He scolded me for not noticing his haircut (?!?)
If it's not flirting, I think it's a bit familiar and socially awkward?
