There are “injustice collectors” lurking in every organization…
He or she is very easily offended. Being offended (hurt, bruised) is a permanent condition.
His or her emotional life is akin to an over-ripe peach. Thus, the slightest disagreement, or your failure to smile (or thank, or praise) leaves him or her with a lingering bruise.
You’ve got to appreciate injustice collectors in exactly the manner in which he or she has trained you, or the fine for offending will be repeatedly demanded. And, even if he or she says he or she does forgive, injustice collectors are not big on forgiveness.
Injustice collectors enjoy being “best friends” which is another way of saying, “you’re mine, I own you, you will love me just like I train you to love me, or I will be offended, depressed, lost, hurt!”
And when “best friend” fails to conform, passive-aggression enters, and alas, best friend becomes “worst enemy.”
Work with one? Keep it light. Sing ditties around them. Don’t fall for it. When he or she tells you, with an accompanying martyr sigh, that he or she is hurt, tell him or her to put his or her feelings away, and get on with the tough job of living.
(I’ve used the bulky “him and her” and “he or she” so as not to offend!)
