Excerpt from today's carpool conversation:
Younger Sister A: Boys can't hit girls.
Younger Sister B: He hits me all the time. [referring to Older Brother B]
Older Brother B: I never hit you.
Younger Sister B: Yes you do.
Older Brother B: No. I don't. I grab you and throw you on the floor.
Younger Sister A: And then the floor hits you. That's okay because the floor is allowed to hit girls.
