A gay co-worker once told me my GAYDAR was better than his. I even demonstrated my ability at a fast food place once, then the guy started talking and my friend went.. OMG! LOL
Because to you, the "odd balls (something "queer")" stood out from the crowd. To him, they fit right in, because that's what he wanted to see - homosexual "normality." He resonated with them - you did not.
