Summer is not obligatory. We can start an infernally hard jigsaw puzzle in June with the knowledge that, if there are enough rainy days, we may just finish it by Labor Day, but if not, there's no harm, no penalty. We may have better things to do.
We've seen what happens when it serves a president's interest to flaunt his faith - which is almost inevitably does, since every poll affirms that Americans want their leader to submit to some higher power.
All our efforts to guard and guide our children may just get in the way of the one thing they need most from us: to be deeply loved yet left alone so they can try a new skill, new slang, new style, new flip-flops. So they can trip a few times, make mistakes, cross them out, try again, with no one keeping score.
Maybe we adults idealize our own red-rover days, the hot afternoons spent playing games that required no coaches, eating foods that involved no nutrition, getting dirty in whole new ways and rarely glancing in the direction of a screen of any kind.
The 1950s felt so safe and smug, the '60s so raw and raucous, the revolutions stacked one on top of another, in race relations, gender roles, generational conflict, the clash of church and state - so many values and vanities tossed on the bonfire, and no one had a concordance to explain why it was all happening at once.
The path of progress cuts through the four-way intersection of the moral, medical, religious and political - and whichever way you turn, you are likely to run over someone's deeply held beliefs.
I live in a dumb house. Which is not to say that I don't love its quirky charm, its drafty windows and leaky fireplaces and an electrical system that protests when too many people are trying to vacuum and microwave at the same time. But charm is not always user-friendly.
Most of us were probably less than immaculately honest as teenagers; it's practically encoded into adolescence that you savor your secrets, dress in disguise, carve out some space for experiments and accidents and all the combustible lab work of becoming who you are.
We know what the birth of a revolution looks like: A student stands before a tank. A fruit seller sets himself on fire. A line of monks link arms in a human chain. Crowds surge, soldiers fire, gusts of rage pull down the monuments of tyrants, and maybe, sometimes, justice rises from the flames.
Runners exalt the marathon as a public test of private will, when months or years of solitary training, early mornings, lost weekends, rain and pain mature into triumph or surrender. That's one reason the race-day crowds matter, the friends who come to cheer and stomp and flap their signs and push the runners on.
It's hard to think of any tool, any instrument, any object in history with which so many developed so close a relationship so quickly as we have with our phones.
High achievers, we imagine, were wired for greatness from birth. But then you have to wonder why, over time, natural talent seems to ignite in some people and dim in others.
The leading cause of death for girls 15 to 19 worldwide is not accident or violence or disease; it is complications from pregnancy. Girls under 15 are up to five times as likely to die while having children than are women in their 20s, and their babies are more likely to die as well.
Virtues, like viruses, have their seasons of contagion. When catastrophe strikes, generosity spikes like a fever. Courage spreads in the face of tyranny.
