Wild Man's first open house

Tonight we will be attending an open house for Wild Man's Junior Kindergarten program. C and I tried to explain it to him this morning, and he was a bit distraught, as he didn't quite understand that he would continue to go to his current school while also going to JK. Having an open house in March when the program starts in September seems very, very early to me. I mean, I doubt Wild Man will remember all of this come September. As for me, I'm alternately excited and sad at the idea. It hardly seems possible that he is old enough for JK.
