Are you happy?

Every day I am surprised by something Katherine says. One of the funny things Katherine has recently begun to ask is,"Are you happy?" She asks this after we have scolded her for something, or if we say something strongly to her. The conversation goes something like this....."Katherine, sit down at table." "Are you happy?" "No, I'm not happy. Please sit down." "Sorry mommy." It gets me everytime - I know I shouldn't laugh, but I just can't help it!
