Spitting

I'm of two minds on this curious habit. On the one hand, it's essentially harmless. Spittle is biodegradable, unlike, say, plastic bags (here's to you, San Francisco), nuclear waste or Ann Coulter's black black heart. It may stain the sidewalk for a few seconds, but it'll be gone by day's end, unlike that empty bag of Utz potato chips 5 feet away from the garbage can on the corner.

On the other hand, it is the act of a person who says, "Cigarette smoke--you may stay; Arbys barbeque beef--welcome to my humble stomach abode; $5 liquor from the corner store--have you met my liver? But you, you loogie, you gob of saliva, you will leave here immediately as you do not deserve to occupy my body." Please, don't put your rejected bodily fluids on display for me.
