because they let you get in the bed with them while you say prayers at night.
because they show you how to make a funny face when your mom takes your picture.
because they ride you around when you can't quite figure out how to steer yet.
because they teach you how to make that cool, indian, mouth-patting noise while you laugh on a swing.
and because they love you enough to let you lay your head on their shoulder while they watch Mickey Mouse Clubhouse with you (even though they think that show is for babies).
Yeah, big brothers totally rock.
