And is it the same person you are talking about in This Other Question
Forgive me, but as I have been re-reading your questions, there seems to be a lot of weird stuff going on with people that may or may not be doing inappropriate things. I think you need to give us more clarification and details, otherwise I can’t help but think that you are surrounded by a lot of strange people, or that you are just paranoid. I’m still unclear as to whether these incidents are happening to you, or to someone else.
If someone (or multiple someones) are doing something inappropriate towards you, then you need to talk to someone in authority, where the problem situations have occurred. We’d like to help you, but we need more information.
