I've posted this before, but it's pretty relevant so:

> My girlfriend(at the time) was in the shower, and thought I was sleeping in bed. I went to go join her, but then decided to give her a scare.

> I silently sneaked into the shower. She had her eyes closed and was washing her hair. I made a stereotypical scary pose with my hands in the air and an ugly face.

> When she opened her eyes she made the most horrible sound I've ever heard in my life. She sounded like she was having a stroke. She fell against the wall and immediately started crying.

> She never forgave me and I think I permanently lost some trust from that little stunt.
