I'm not sure if it's them or me 
I belong to a club with about 100 members, probably 60 that attend regularly (in normal times). I'm good friends with maybe a dozen and friendly with most.
However, I find the ones about whom people say things like "oh he's such a nice guy" or isn't "she lovely" get on my nerves, their niceness seems fake to me, no one's lovely and smiley all the time, but no one else seems to see it.
It doesn't matter, it's just an observation about my own response to people I'm perfectly pleasant and polite to everyone but I do seem to be the only one who doesn't seek out the company of the lovely people.
