I have always admired people who are genuinely social

[Urbane Guerrilla]

I am affable and sociable; pretty much the opposite, emotionally, of Undertoad at his OP.

This does not make me a piano-grinning gladhander on all occasions. But it does make me capable of a small talk that often as not leads to a deeper category of speech. I can push into a group if necessary, and I can make people happy I did.

Charisma is not inborn; it is a social skill that can be practiced and it can be learned. Some of those kids you envied socially back in the day were naturals at it; I was not.
