It's hard to be depressed about rainy days when there's someone in the house who gets excited when he sees rain. Rain jacket: check (L.L.Bean, bright yellow). Rain boots: check (L.L.Bean, bright yellow). Umbrella: check (mom's collapsible in red-and-pink polka dots; doesn't seem to bother him a bit).
And I let him splash in puddles all he wants, because that's what I wanted to do to when I was his age but wasn't allowed to.
