Our parents are still alive and..
I can't say that they are sane.
Mom's sense of humor is much like my own.. which is much like my sister's..
My brother DID fall off the roof once.. okay so he fell off the roof repeatedly.
(Sis corrected me.)
We were shoveling snow off the roof because we were having repeat blizzards and the roof would eventually cave in.
What does my brother do?
He first shoves me off the roof.
(I landed between the house and the car..)
He's now "king of the Roof" and what does he do?
He turns around and then falls over his own two feet, slides almost the entire length of the roof freom peak to edge and falls off.
And bounces off the car parked in the driveway.
He's also the one previously mentioned somewhere who wizzed on the electric fence.
