lost my phone

So I lost my cell phone. Completely my fault......I was negligent & lazy.I don't even know for sure where I left it in office.I left office at 7:20. When I sat in the car, I looked for my phone. It was not in my purse. I assumed that I had left it on my desk. So I went home & the first thing I did was called up office. The security searched for my phone & did not find it anywhere. Abhi said that he was also trying to ring me up. It was ringing in the beginning & then was switched off. So for sure someone stole it. I was still hoping that maybe the battery conked off & thats why it may have got switched off. But i searched the office today & its nowhere. :(
