Phones in the bathroom

Today I had a voice mail from my sister all I could hear was the sound of the the toliet flushing and then running water. She pocket dialed me while she was in the bathroom. My first thought was that's just wrong and then I started to wonder how many people leave their phones in their pocket when using the bathroom. I know I don't for fear that it will fall in! I did get a good laugh out of it and its better that she called me and not her boyfriend!
