    In the event of an oxygen shortage on airplanes, mothers of young children are always reminded to put on their own oxygen mask first, to better assist the children with theirs. The same tactic is necessary on terra firma. There’s no way of sustaining our children if we don’t first rescue ourselves. I don’t call that selfish behavior. I call it love.
