I think it's more correct that people appreciate being liked. If you don't feel liked by this person, you'll gravitate to a different person. Calling it "servility" is really stretching it.

> seem 'interesting' without saying much is to elicit intrigue - or mystery, so you want to seem mysterious.

I'm sure there are people to whom that applies. But it doesn't seem likely to be widely applicable to me. Most people just aren't going for the "dark and mysterious" vibe.
