Let's see....when I was about 10 my grandma told me I was cold, and she worried I had no feelings, like a murderer. Seriously, she said that to a 10 year old....I have forgiven her for it, realizing the circumstances (family deaths). It stung only because it was my grandma; I know I have feelings, very deep ones.
Since we were children, my sister's favorite low blow in an argument is to tell me I have an ugly, unlikable personality & no wonder I have so few friends. That never fails to sting because a secret fear of many INFPs is that they are unlikable once people get to really know them.
Being told I am so thin I am invisible, a beanpole, must be anorexic, etc (I am not THAT thin).
I was called "snobby" by an ex-friend to other people - which made me mad because it was slander. In general, people refer to be as being snobby/aloof and cold, but will retract the impression upon getting to know me.
The other insults were pretty typical playground stuff. Has anyone ever NOT been told they were ugly by some snotty 7th grade boy?
