What do city kids do when it gets so hot that your eyelids sweat? Mini-critic hit the water with his best friend, of course, in the sort of temporary pool that is one step up from what we have seen other city kids using for a pool, a recycling bin and a hose. Happiness is watching kids in the water, and if parents can dip their legs in the water, too, so much the better. We had a brief reprieve earlier this week from the oppressive heat of the Washington summer, but the last couple days have been dangerously hot. It looks like we will mostly be under the 90-degree mark in the week to come, thank God.
