grow up and blow away

Today after I got home from school, I played Rock Band with my brother and then we looked up cheap watches on eBay for him to buy. While I was sitting on his chair, he stood beside me and leaned on my shoulder. I don't know why, but I've always loved it when he leaned on me. Like when we were in the car and he'd rest his head on my shoulder because he was tired. He is growing old! We're both growing and it's strange and weird.
