Is it maybe because NTs lack empathy?
I mean in general, not everyone, of course. They certainly appear not to understand my point of view when I say things like 'We're not having a birthday party for our daughter, because we#d prefer to do something as a family, instead'. They assume we're mean or lacking in cash and try to persuade me that it's not so expensive, totally missing the point. They don't get that a family day out means more to our daughter than a day with school 'friends' at softplay. I thought we were the ones lacking empathy. Weird.
