According to my son, it is acorn and chestnut picking-up season.
He displayed unfettered delight when he spied the first chestnut of the season-- a beautiful, smooth round chestnut. It signalled the first time I had witnessed him remember a season. A season before that had included making a friend--a friend to pick up chestnuts with. Now, that is what the memory of a season feels like, smooth, round and perfect in his little hand.
