I don't think I've mentioned this before, but last summer we started collecting rocks from the places we visited with the kids. I was hoping that it would give them a trigger to help them remember things we had done as a family. It seems to be working. The rocks are on the windowsill above our kitchen sink. Sometimes Sean catches sight of them while helping me cook or wash dishes, and tells me about them and where they come from. We've got a "special rock from the beach", a "special rock from Maudslay park", a couple of "special rocks from the Saco River", and a "special rock from the mountain". I'm hoping to keep this up next year. Who knows, maybe it will eventually lead to an interest in rock-hunting or geology. At the very least, though, it gives him a way to remember special moments we had, which is enough for me.
