My parents never told me my IQ. They were afraid I would turn into a monster (and given their parenting skills, that wasn't a bad instinct). I learned it from my spouse after she talked to my mother.

Problem is, I thought I was just 'smart'. If there were things I struggled to understand, it was only natural for others not to get it unless I could unpack it for them.

However I also had this notion that when I understood things immediately that I was just 'faster', that in five, ten, fifteen minutes they would figure it out and we'd all be in agreement and everything would be great. Everything was not great, and I would get visibly agitated with people for not getting these completely obvious things.

These are not realistic expectations and certainly are not attractive behaviors.
