Still don't have my cell phone.

I lost my phone tuesday at school, and I looked for it then. I was only in three areas, but it wasnt there. I called it and wandered around hoping to hear it, too.
On thursday, I went to four different offices (three of them in the building where i was tuesday) and none of them had it. I left my information at two of them.
I've tried calling it a lot, but it just rings and then goes to voicemail. Nobody answers. I'm getting sad.
Where is my phone?
