I think he's made a decision!
On the way home from the admitted student's visit, I urged him to really think about what the different options have to offer and where he sees himself being successful. (He hasn't really been too excited about thinking about it/talking about it, etc. He's narrowed it down tot he top two, but beyond that...)
Anyway, I urged him to set a date in his mind during which he'd make a decision -- maybe by this Friday, the start of spring break. Then, live with it for a week or so. If he's still confident in his decision by the end of spring break, we'll put money down. If he's not then we'll figure out what to do next -- revisit, ask more questions, whatever. I just don't want him waiting till the last minute and making a knee-jerk decision because the deadline is looming.
This morning he said "I think I've made my decision..." The school he's (tentatively) chosen doesn't offer any benefit for accepting early, so we're still going to wait till after spring break to pay the deposit... but I am glad he's made a decision. Unfortunately, it's the one that's farther away from here (about 2.5 hours... so not "far" in the grand scheme of things, but the other option was close enough that he could have come home for dinner if he wanted to. But, I do think he's making a good decision. Hopefully it will "stick.")
