D.F.W.

Again, please don't think that I'm giving you moral advice, or that I'm saying you're "supposed to" think this way, or that anyone expects you to just automatically do it, because it's hard, it takes will and mental effort, and if you're like me, some days you won't be able to do it, or you just flat-out won't want to. But most days, if you're aware enough to give yourself a choice, you can choose to look differently at this fat, dead-eyed, over-made-up lady who just screamed at her little child in the checkout line—maybe she's not usually like this; maybe she's been up three straight nights holding the hand of her husband who's dying of bone cancer, or maybe this very lady is the low-wage clerk at the Motor Vehicles Dept who just yesterday helped your spouse resolve a nightmarish red-tape problem through some small act of bureaucratic kindness. Of course, none of this is likely, but it's also not impossible—it just depends on what you want to consider.

—You might already be sick of this speech, but it works for me.
