This afternoon, the phone rang. I picked it up. The voice on the other side said, "Can I speak to Andrew." I said, "This is Andrew." Then the phone went dead. And then nothing. No call back to say something like, "Hey, sorry about that, the phone just went dead," or whatever.
Now, I'm not really paranoid. It's just weird. My guess is that either they got disconnected and lost my number or I am about to be served.
Or maybe it was a secret admirer who figured out your phone number and wanted to see if it was valid. I only suggest this alternative as I've had it happen to me before.
