No one should ever be forgotten. Not even rotten silly asinine boys. To be forgotten is the worst thing in the world. It means that you never really held any importance in someone's life, because you are so expendable in their memory.
Boys can do stupid things that need to be forgotten in themselves. They can hurt, lie, and cheat just like girls do. Boys can cause pain, and make things all messed up. The good memories should prevail if this boy is worth thinking about.
Forgetting about boys is too hard, because it requires thinking. Thinking about forgetting? Hmmm.
