Because it's so elementary?

There’s something paradoxical about your comment… :)

it's really not. It's easy for some, sure and you're maybe one of them (or perhaps mistaken!) but many, many MANY people, especially men, even intelligent men struggle with social situations and maintaining healthy social relationships.

Be nice? Don't be a know it all? Even if you don't believe it you've surely heard people say it sometime in the last 40 years. Autism notwithstanding, and that probably accounts for a decent share of the readership

I am, and don't ... but that still doesn't mean it doesn't take effort. There's way more to it than smiling and not being a complete tool.

How long has it been since you called your long lost best friend and caught up? Did you go to his brothers funeral? Check in on him after his divorce? A year after his divorce? 5?

It takes effort and is far from elementary no matter how much rizz you have.

I agree it's effort it's just not hard..... for a 40 year old, remember.

It is for many empirically.
