A bump

Samantha came home from school today with a huge bump on her head. She said she walked into a pole and went to the nurses office 2 times because it hurt so bad. I thought it was odd that no one said anything to us. Jon picked Sam up and the teacher didn't say anything to him and there wasn't a note in her folder. I can understand a little one but this thing as big as a silver dollar on her forehead. Well I guess she isn't in preschool anymore!
