When I was young I missed so many signals (though I dare anyone to understand the signals sent by a teen tomboy) I married the woman whose first move was a hug
After being married, then after being divorced and too broken to date then I saw every signal, but they all quietened down (or I was missing them) when I was ready to date again
Some non-signals are pretty bold though - at a recent music festival a woman wanted to kiss every man present. I’m not up for cheating so I dodged her
