I have to agree. The way I see it – he’s done applying to colleges, and he’s not making a decision right now, right? If that’s the case, then him being super-excited or miserable over college decisions right now does not mean anything. Some people enjoy talking on and on about colleges (hello!) just for the sheer pleasure of it, but a lot of people don’t. What’s important is that he’s ready to make a decision later when the time comes. It doesn’t sound like there are any deadlines looming, so honestly I don’t think there’s anything wrong with not worrying about it now. It’s not as if there’s anything he can possibly do to change which schools accepted him or which schools deferred him. It’s not “senioritis”, it’s just being level-headed.
