Most people have at least one or two redeeming qualities, as in,

Person 1:  That guy's a jerk.
Person 2:  Yeah but he sure can hold his liquor.

I think I know a person who has absolutely no redeeming qualities.  I was thinking this morning, "That woman is so mean.  But at least she...  Well she has...  That one time she...  Nope.  She's the meanest, grumpiest, most awful person I know."  But I'm still nice to her, hoping that one redeeming quality will someday become evident. #sociology
