"Give.  Receive.  A little rough-and-tumble, once in a while, is fun.  Besides, I'm...uhm...no offense to Daisy, but I'm a bit tougher than she is.  So I can take more before I really feel it.  And sometimes I sort of forget my own strength and put more of the smack down than I want.  But I'm not into actually causing serious pain or anything like that.  I only really enjoy hurting people I don't like."
