Brooks' natural facial expressions always look sooo glum and sad. He tends to be very serious when he is involved in an activity so he shows very little excitement when he is actually doing something. Whether he's having fun or not he always looks miserable. Even last summer when he visited Rob's sister in Atlanta she said she wasn't sure if he was having fun because he doesn't show it. He had a blast, by the way.
The rare moments when he really laughs and shows that he is having fun are sooo cute. I think I'm going to have to find a way to force him to loosen up!
