Lightning likes to do what Filou does every time I go into the bathroom. Our bathroom door doesn't shut right, so he knows how to open it, too.

JJJ3,THOUGHT,I WAS DROWNING,IN THE SHOWER,AND WOULD WAIT OUTSIDE,UNTIL I GOT OUT,MEEEEOWING,ALL THE WAY.
Lightning does this too. He gets up on the side of the tub all the way against the wall where the water can't reach him. I told him one of these days he is going to fall in and get all wet. So right after I said that, he trips and falls in!!!
