Today Cakes and Cookiemonster got into a little tiff. Cakes started it by hitting, kicking and poking her brothers eyes. He responded by bitting her knee, not very hard but hard enough to get her to leave him alone (and he immediately told her he was sorry). Cakes came running into me and kept bawling and bawling about how much her knee hurt. I decided to try to get her to laugh and told her "oh, that's too bad, do you need knee replacement surgery?" and her reply was "yes, I want a purple one"!
