What does Robb want?

This summer I have asked this question multiple times....So what does Robb want?..... I wish I knew. We have left Robb at home for 2 trips this summer, and it kills me that we can't take him. One is two a bluegrass festival, Grey Fox, and he has gone all his life. He loves the music, but my parents think he just isn't going to have such a good time....it can get hot, and we wonder if Robb is really having as much fun as he used to. Also it is during school for him, and it is a pain for my to to have to carry him around during the festival. He is a part of the family though, so this will have to hurt him!!! To me it feels like he is being excluded from family experiences!!! This is an on going internal conflict of mine, but the worst part is I don't know what he wants. So the only thing I can do is hope Robb remember's how much I love him because when he is happy I can't be anything else, but the same. I guess that sounds a little selfish, but all I can see is a win, win!!! :) :)
