To be honest, even if it was flirting I'm too dumb to pick up on it.
This latest craze with male height is bizarre though. Something about the magical "6 feet tall" height seems to have become part of the zeitgeist and the rest of us males are apparently as desirable as stuff one finds in the "discontinued" bin (Like expired canned gravy, or rock hard Twinkies I guess - who looks in those bins to begin with?). I know height has always been a thing, but I just didn't realize there was a meeting where it was decided what thing it should be for everyone.
