That's extremely well put, and pretty much matches how I felt this christmas. My son was visibly tired of all the presents, he practically had to be made to open some of the later ones. For a kid who doesn't really like any kind of "performance" it seemed pretty draining.

I think I'm going to start broaching the idea of pruning his collection a bit over the next few months, or at least boxing some of them up like you've done. I like that idea, it's a nice half-way house, and doesn't force them into a situation of having to actually get rid of things.
