Did you ever notice, especially in some of the earlier seasons, the girls are usually sitting on the couch, while Bonnie is delivering a line. She strolls behind the couch, and puts her hand (or hands) on top of one of their heads, or sometimes she messes up their hair, or slaps them gently, OR one time, I swear she started pounding her fist on their head that I was worried they would get a mild concussion. I realize maybe she is trying to convey affection to show that these are her daughters, but I know she is an actress, and that these aren't her daughters, and maybe she just might be using their heads as a prop! Seriously, it irks me every time I see her tapping their heads! LOL

I've seen her pound them on the head a few times!
