For the last couple of weeks, I've been hearing large thumps in the house that I can't explain. It was getting the dogs worked up, and worrying me a bit too. I like to know the source of noises that loud, especially when they happen so often.
It took me a while, but I eventually figured it out. I still don't know the why, but now I know the what (or maybe I should say the who).
Himself has been dive bombing into the tub, and then rolling around and chasing an imaginary mouse. He's been doing it a few times a day, and sometimes he even calls out as he plays. It doesn't last long, though. Ever since I figured out what he was doing, he stops as soon as the dogs and I arrive to watch.
I figure he's playing mental games with the rest of us, to see how much how worked up (therefore into how much trouble) he can get the dogs, and/or how long it takes before I drop what I'm doing to come find him.
