The specific instruction is "how" to accomplish that goal, not that the goal exists- obviously, the goal exists for the reasons you specify. The difficulty is how to get there, which is extremely hard, doubly so for a brain that doesn't necessarily have the archiecture required for fully understanding the restraint, thoughtfullness, empathy, etc. of being friendly/well-liked.

The ability to be friendly in adverse situations is absolutely a social skill. I have a couple of coworkers that have the ability to remain friendly even in intense situations. I find it really helps deescalate situations (or keep them from escalating in the first place) without derailing the conversation.

Still, being "friendly" and "well-liked" is an important skill for later. People tend to not want to work or have sustainable relationships with people they can't stand.

It's probably poorly phrased, but I think we've all met people who just ∂on't really know _how_ to be a friendly, approachable person.
