Bicycles are dangerous.

Mr Chun, from Kevin's school, took us to dinner tonight at his sisters restaurant.  During dinner, I tried to tell him about my story of the boy kicking the other kid and how I sat him on my lap and hugged him (story below).  He looked at me with a very concerned look on his face and said... "yes, bicycles are very dangerous.  Alexis, be careful."   As you can imagine, I had to do everything I could not to start laughing!  Where the heck did bicycles come from?
