lost his phone

Today I did not have my cell phone with me because my husband had it. He lost his phone yesterday at work and he could not find it. He said he was looking every where yesterday but he still could not find it. I was wondering why he never answered my call. He could not call me from the phone at work because he does not know my number. Weird huh! So today he brought my cell with him but when he got to work somebody had turn his phone in to the lost and found. He was worried last night and could not sleep thinking about his phone. I told him nobody would keep his phone since it was the cheapest phone in the store. He was worried only for all the phone numbers he had stored on it.
