This is not for the faint of heart. I had just sat down to lunch today and the school called to tell me Tim had a "collision". What is sad is that the little girl he ran into, has the exact size bump in the exact same place. Can you say concussion! They didn't think I was very funny when I called them the Unicorn Twins. This is the biggest goose egg I have ever seen (and believe me, in my line of work, I have seen a lot of them!). I will be on concussion watch for the next 24!
