A nice person shows gratitude and respect. They are without deceipt, ulterior motives, and lying. They do not gossip. They are kind to others, any others, even strangers, without needing to 'show' or asking for something in return. They do not ignore when another is hurt/crying and they listen, not judge. They're not discriminatory and show acceptance based upon another's merit. They do not operate by 'status' or 'power' but my genuine logic. They are polite. If they make a mistake, they apologize with sincerity. They don't hold grudges or make assessments of other's who are in need. They are truthworthy so another doesn't ever have to worry about the 'nice' person using information as arsenal. They try to be supportive, even if it's just listening. Professionally, a 'nice' person acts, well, professionally, using ethics to further the need of their objective without using others or 'cheating' on their data. I think nice people try very hard and are not lazy; giving what they can give/contribute.
I must say, in general, WP inhabitants are probably the 'nicest' group, by definition, I've known. I know Auties/Aspies can be a pain, or maybe that's just endearing - your call. But they are genuine and true. That's nice.
