Picture this...
your sitting in a car going to see your brother you haven't seen in 8 years. Your wondering what he Will say when he sees you. Maybe he'll hug you like it was just yesterday you saw him, or maybe he Will walk away and wont say anything. Maybe he Will just talk to you right away. You wonder what the look on his face Will be when he first sees you. Maybe he'll be shocked, maybe he'll think your weird, or maybe he wont like you because of the things you wear.
Though you don't realize, hes probably wondering the same things.
But once you see him your shocked, hes exactly the way you pictured him. Hes very smart, and all the time you have to spend with him doesn't seem like enough. So all you have to do is make the best of it. laugh, play, talk, do anything that the both of you Will remember.
