Yay! I found my phone. It was of course in the one place I had not looked: on my bed. I had not looked there because when I was looking there were people sleeping in my bed. So this afternoon I decided to call it one more time. I heard it vibrating and lo and behold there it was. It must have fallen out of my pocket last night when I was laying on the bed talking to my mom (on my home phone). Well at least that is one worry put to rest.
