A person cannot control other people's actions the way they can control their own; and that's one of the few reasons I can't berate other people for their mistakes to the extent that I can berate myself for my own. Indeed, for that same reason, when I make mistakes, my response to myself is little more than the vilest of fury: the ability to act correctly (including the ability to learn it) was within my own nervous system, yet I clearly neglected to use it.
(For example: previously this comment contained several typographical errors. Rereading the comment repeatedly, revealed each typo ... but there's no excuse for any of them to have even escaped the keyboard.)
