At school in the seventies, describing someone as "nice" was to sneer at them for being wimpy, compliant, a "goody two shoes"!
Even now I'm not drawn to people who try too hard to be liked, who fit in, who don't like ruffling feathers.
But I do know, respect, and value being able to spend time with some really, genuinely nice people. I want to be more like them. We need more people to be more like them.
