My brother likes to play soccer. He also likes to build things and make origami animals. He plays with our dog, and he’s growing a cactus in his bedroom window. He has lots of friends, but he also has an enemy. His body is allergic to peanuts and tree nuts. His nut allergy is a dangerous enemy, so our family wants to learn all we can to keep him safe. Do you know someone with a nut allergy like my brother?
