I am afraid that I had a terrible with doing this kind of thing recently. I was in line at a restaurant & saw that the young woman in front of me was wearing letters... she had them across her butt, which I hate, but I know that is the fashion now. (Lordy, I sound old!)
I tapped her on the shoulder & asked if she was a Theta, assuming that she WAS. I was SHOCKED when she said "No, these belong to boyfriend's sister and she let me wear them."
When I said quietly "You really shouldn't be wearing them if you are not a Theta," she just flipped out on me! Started almost yelling at me. Almost makes me scared to ask anymore
