Time. I love how elastic it is in Summer. That my kids can ask for hard-boiled eggs all the way to eggs benedict for breakfast – and I don't have to calculate time-to-bus. Mind you, while I'm making this breakfast they are upstairs cleaning their rooms. And I've already sent one back upstairs with a stern warning about what will happen if I don't see the level of effort I expect in said room cleaning. Ah, time. It works for all manner of things in Summer.
