He's 6

He had another birthday. Now he's six. He goes to kindergarten. He's learning to read. He loves everything about school. Except waking up in the morning. He loves to collect things. Anything. Especially things that no one wants anymore. And he wants to be a secret agent. He loves guns. He got some new nerf guns for his birthday. He is a really fun kid but can throw a major fit when he deems it necessary. It's like nothing I've ever seen before. But he gets over it pretty quick. He's such a great kid. Smart, funny, passionate, kind. And growing up too fast. Is there any way I can slow this growing up thing down a little?
