Sam always looked forward to sleeping over at his best friend Josh's house. They had been classmates for a short time, but they formed a great friendship rather quickly. Sam packed his sleep sack and some toys, and then his mom dropped him off at Josh's house. Josh greeted Ryan on the porch. They started playing right away. First they rode bikes. Next they played tag in the back yard. When they were tired they went inside. As soon as they walked in the house, Sam's eyes starting getting red and itchy. He spotted a dog sitting on the couch. Sam started sneezing uncontrollably. ""I'm sorry, Josh. It's been a lot of fun, but I have to call my mom."
