I tripped

Okay he totally got grounded for this, but I think its hilarious.... I had to fight back the laughter when I was getting mad at him....
William: "Matthew I'm a vampire and I'm going to suck your blood" (menacing laugh)
Matthew: "No I will fight you because I'm a Jedi."
Then the sound of the two of them slap fighting... Then Matthew screaming bloody murder..
Me: "WILL GET IN HERE!"
William: "I tripped and accidently bit Matthew and made him scream."

So he got in trouble for 1. He knows better than to BITE, seriously and 2. He lied, I heard what happened. Not okay to lie....
