Missing

One red bike with silver words. I got a call from the school this afternoon while waiting for Rehm to come home. His bike is missing. Seems that there have been several instances where bikes are missing in the afternoon and back the next morning. I have a very sad boy who keeps telling me "I told you so!" He has been asking for a bike lock for months and we haven't felt it was necessary. Honestly I didn't want to deal with him forgetting a combination or how to unlock it or losing a key. But now it looks like we will be getting a bike lock and possibly asking Santa for a new bike.
