You ever wonder what a class in matrices is about? Yeah, me, too. I'm still not sure. It has something to do with linear algebra. I skimmed through the wikipedia article on it, but it's not any more clear to me.
Yesterday I went to Baltimore with the kids to meet their newest cousin, Naomi. She's a doll and my brother and sister-in-law seemed calm, even with a house full of visitors, young boys (it seemed like all of Oliver's cousins were there--and they're all boys, too), and a new baby. They're going to be busy for awhile, those two.
Today it's more EdPsych.
