At first I thought that the phone call itself was the trigger for Bumblebee. Nope, she does nothing when other calls or texts come in. Next I thought it might be the time of day. Nope, it happens at any time of day. Finally I wondered if there was something that I was doing to trigger her. Nope, I have tried deliberately doing very different things and she always reacts in the same way.
Last night Eric and I were talking about this phenomenon and he mentioned that earlier in the week he had watched out the window as my dad pulled his car around the corner, two blocks down, and Bumblebee ran to the window. There was no way she could have heard or smelled anything, yet there she was anticipating his arrival.
So what's the deal? Is she psychic? I doubt it because she wouldn't bother begging for food unless she knew it was coming. It's a little bit spooky.
