Last Day of Childcare

Tomorrow is the last day of the summer childcare circuit.  All the camps, all the babysitters, all the parents and grandparents: it's all worked out perfectly, not a day's problem, not a lost child (literally or metaphorically).  After tomorrow, I'm with the girls for the rest of the summer (give or take a meeting or two), and we're good.  So when does our luck run out?  Tomorrow, of course.  S has to work early; I have to work late; all three babysitters are busy.  I'm choosing to take this as a sign that I should gratefully appreciate how well everything has worked out so far.
