Here's a new one (I think): My husband tried to call me yesterday at 6:30 but the phone was on vibrate and I couldn't hear it ringing. 1 hour later, he's home, walking around the house and says "your phone is vibrating." Takes it out of my bag, hands it to me and I look at it and tell him that he's calling me - his phone must have accidentally dialed. He takes out his phone and says he's not calling. I stare at the phone puzzled and it just keeps buzzing and buzzing like he's calling. Finally, I answer and no one is there. The thing must have been "ringing" since he called an hour earlier. Verified that that was the last call in my call list. Weird, right?
