If you pull my hair, I will...

...blow in your face.  Elizabeth's teacher told me that one of her friends pulled her pigtail today, which made her cry in class.  Her teacher said that she was upset for some time.  When she came home, she was in a bad mood and instead of saying her friend pulled her hair, she kept telling me that she blew in her friend's face.  We've talked to her about hitting, sharing, playing nicely, and apologizing, but how do you explain to a two year old that blowing in other's faces shares germs and that she should not do it.  A two year old needs to express their anger too.  We didn't scold her about it this time, but soon we'll talk to her about it.  -S
