.I bought a mini cargo van from a quadriplegic the other day.  I talked him down from 3700.00 to 3000.00.  As is normal for me, I researched the vehicle after the fact and found that it's worth only 2700.00 in excellent condition.  Now, my ethical dilemma...Which is worse? That I bartered the price down on a guy who fell off the pommel horse onto his neck back in '86 and clearly  needs the dough? Or that he used his "condition" to inflate the value of the van, assuming that I would feel sorry for him and pay his price?  Or is it worse that I would think that he would use his "condition" to get more money in the first place?  Or is it worse that I told him if the van broke down I would come back and kill him?  If this was the animal world, he would have died as soon as his neck snapped, because of the "survival of the fittest" law that prevails in nature.  Then, I wouldn't even have his van.  I  would have paid the 3700 for a hunk of junk to some giant ape of a guy who could have ripped me to shreds if I so much as looked him in the eye for too long.  And I'd be regretting every minute of it.  Stewing.  Stewing in my juices....Plotting.....Forever plotting....Doing nothing.
