  They fight so much, and over such trivial things, that it's almost funny. Today, it was downright hilarious; I convinced the two to watch Timeline with me (pretty good movie, by the way. I didn't like how so many of them died in the beginning, though...) and all of 20 seconds after it's over, David (9 years) has insulted Brian (12 years) and thrown a pillow at him. And then this morning they were fighting because they each wanted to play a different game, and were struggling with the concept of "compromising. " Of course, they couldn't go read a book (gasp! ) or anything else not involving each other...!
