Jenny is my best friend. We both play volleyball together. We’ve been playing volleyball together since 7th grade. I’ve noticed that every winder Jenny withdraws from her friends and always seems sad. Every winter, I think that it’s me…that I’ve done something to Jenny to upset her. Once spring hits, Jenny slowly returns to her “normal” self. What do you think Jenny could be suffering from? What advice would you give Jenny?
