Someone put a hidden camera in my bathroom

I suspect it is one of my friends or family members, I think they got together years ago and did this and broadcasted it live on the internet and have used it to torture me. Now a random stranger has joined the fun.

Everytime it never fails if my ass is naked and in the shower my phone will ring, it doesn't matter when it is it will happen. Today I had a late start to my morning, it is freezing here, the last time I checked it was 5 degrees and that was without the windchill. So finally 11am I got into the shower and guess what my phone rang, go figure. I stop and stand quietly to see if I need to make a mad dash for the phone since I have yet to learn to take it with me. Maybe I should put a phone in the bathroom, do you think it would give people the impression that I am on the toilet when I answer my phone? How gross of a thought that would be. Well whoever had called didn't leave a message and I went back to enjoying the scalding hot water. Then it rings again I thought it could be my kids calling and was confused as to why I didn't previously answer. I grabbed my towel and carefully but quickly make my way over the linoleum tile. My dining room is like an ice skating rink with wet feet. I pick up the phone "Hello" *Pause* "Hello" *Longer Pause* "Hello" *I hang up* I Say a few profanities and quickly finish my shower.
