I take public transit so I can look at girls' feet.
Do you have a foot fetish?
I guess I do. I find feet so interesting.
Ogling other people in public is rude and inappropriate behavior. While it is okay to have a foot fetish, it isn't acceptable to creep on others in public because of it. You should keep your fetish to consenting romantic partners rather than involve unwitting people in public.
What is wrong with looking at feet? It's not illegal to do that. Besides, if I am pretending to look at her face, I don't think she'll know what I'm looking at anyway.
People do notice especially when you are going out your way to do it. You should stop before someone calls you out in public.
