OK. I've just had one of the more bizarre experiences in my life.
I was outside having a cigarette when a big grey tabby saunters up the driveway. There is a five foot wall separating our home from our neighbors. I've watched many cats take a leap over the wall... easily. Well, this tabby cat leaps up but can't clear the top of the wall and falls back on his ***!
He, then, proceeded to walk away into our back yard. On a whim, I said out loud, "You could try again!" Immediately, he stopped... looked at me... then went back to the wall and lept again. And, again, he failed to clear the top and fell back on his ***. He gave me a very dirty look and walked away into the darkness of the yard.
I think I made him mad!
