“Going to dance at my wake?” “I don’t dance,” the lawyer answered, “but you tempt me to learn.” - Robert A. Heinlein

She taught me to love by loving me, and I learned — rather slowly; I wasn’t too good a pupil, being set in my ways and lacking her natural talent. But I did learn. Learned that supreme happiness lies in wanting to keep another person safe and warm and happy, and being privileged to try.

Two bodies attract each other directly as the product of their masses and inversely as the square of their distance.' It sounds like a rule for simple physical facts, does it not? Yet it is nothing of the sort; it was the poetical way the old ones had of expressing the rule of propinquity which governs the emotion of love. The bodies referred to are human bodies, mass is their capacity for love. Young people have a greater capacity for love than the elderly; when thy are thrown together they fall in love, yet when they are separated they soon get over it. 'Out of sight, out of mind.' It's as simple as that. But you were seeking some deep meaning for it.

A feature that struck my eye was an abundance of built-in bookcases…added later, it seemed to me, except a pair of small ones flanking the fireplace in the family room. Most houses didn’t even have that much, as most people don’t read.
(Before the twentieth century was out that could be worded, “—most people can’t read.” One of the things I learned in studying the histories of my home planet and century on various time lines was that in the decline and fall that took place on every one of them there was one invariant: illiteracy.
In addition to that scandalous flaw, on three time lines were both drug abuse and concurrent crime in the streets, plus a corrupt and spendthrift government. My own time line had endless psychotic fads followed by religious frenzy; time line seven had continuous wars; three time lines had collapse of family life and marriage—but every time line had loss of literacy…combined with—riddle me this—more money per student spent on education than ever before in each history. Never were so many paid so much for accomplishing so little. By 1980 the teachers themselves were only semiliterate.)
