Cell Phone Troubles

Oh, boy............My stepmom found my cell phone on Saturday the 17th, it was in my pillow case. I thought that I had it with me when I left, but when returning home from shopping with my dad, I realized that it was gone. My stepmom claimed that she was going to change the sheets on my bed. Hey, was that before or after going through my backback? She not even descent enough to put stuff back the way it was, so I knew she had gone snooping through it. She has not changed the sheets on my bed in um, let me think, oh ya, like FIVE YEARS. So, gee, I was going to be gone for three hours, and in that time sharon decided to "help me out"..............B.S. So now my dad it threating to smash the phone with a hammer.
