Coincidence of common names

Today my cell phone rang with a 405 number (Oklahoma). I didn't recognize the number, but I answered it anyway. Here is a transcript of the conversation:

- Hello?
- Hi... Michael?
- Yes?
- Is Amy there?
- No... She is not here...
- Oh, is this the (a name I won't write down)'s residence?
- No...
- Oh, I'm sorry, I must have dialed the wrong number.

Yes, that proves that both Michael and Amy are very common names. I think my name should be Michel from now on.
