Conversations with Lily

M: I can't believe what a mess you guys made in here. (referring to the pile of toys in our living room)
L: Yep, you have to clean it up all by yourself.
M: Um, no. Who made the mess?
L: Me! (points to herself)
M: So, who has to clean it up?
L: You! (points to me)
M: No, you made the mess, so you have to clean it up.
L: No, it too hard for me.
