I hate it when difficult child obsesses over things (which is all the time). For example, about 10 minutes ago easy child/difficult child told difficult child she was going to buy herself a Wii game and that he couldn't play it (yes, she was being a pita). Ever since he has been asking her why he can't play it when she gets it, can he please play it, he'll be gentle with it, he won't sell it, I'll go ask Dad if he'll buy me one. Argh....
