> And if it gets too much, “sorry I gotta call my boss” is a believable excuse to get out of anything you find awkward or if you’ve had enough. Knowing you have that parachute might make it easier.

Unless this is true, I don't think that's a great idea.

Don't be pathetic and lie. Be honest. What's wrong with saying "Sorry $NEW_PERSON, I have to go. It was great to meet you."

If you're interested in the negative effects of "white lies" I'd recommend picking up Lying by Sam Harris.
