The Band-Aid

I picked up the kids from school today and in the car on the way home they told me about their day. Gillian said "John got a ban-did." I said "I saw that. John what happened?" John said "I fell and got a cut. And it was bleeding. I can't run fast now." I asked John to tell me what happened. He said "I jumped and fell." Gillian elaborated "John was running around. Him jumped off the wood. Then him get a band-did. Him has a boo-boo. I don't have a boo-boo. Him does. Him has a band-did."  Thank you Gillian. That was very informative.
