That would have made me cry too :( My brothers used to sneak into the bathroom while I was showering and pour cold water on my head... I still have huge paranoia when I shower. If my husband comes into the bathroom too quietly while I'm showering and turns on a faucet or does anything that will suddenly alert me to a presence I scream.

That's a really horrible sort of thing for someone to do, what this girl did to you. For most people, this would be a huge shock to the nervous system, I would think. I hope she understands that it wasn't a nice thing to do and doesn't do it again.
