I agree that secret admirers are creepy. I recently had a guy get my number off Facebook and text me. I hadn’t even realized it was on my profile, but that’s a whole other issue.
Anyway, when I asked who he was, he said something like, “FaceTime me and find out!” I was like “No thanks, I don’t like surprises.” Then I blocked him.
I later learned who it was, and I explained that this was NOT a good way to approach a woman.
