I never trust anyone who, upon initial meeting, gives me compliments. I have a little voice inside my head that responds, "But you don't know me well enough to compliment me." If they are too free in giving out compliments, big red flags go up because they want something from me.
A compliment from someone who knows me...is sweet.
Criticism comes in many forms - on one hand, it is a tool for bullies and abusers and on the other hand, it can be used as a bridge for better understanding of an issue, a skill or process, or a personal relationship.
Unfortunately, it is most commonly used for the first purpose I stated. I don't respond well when someone uses criticism to belittle or abuse me.
And what really gets my blood boiling is when I object to unfounded criticism and they respond with, "Oh..you sure don't take criticism well." Really ???? Well...no shit, Sherlock.
