These people are so desperate that they don't mind humilating themselveslves

Who Nick?
Who are these people?

Downstairs neighbor.

Ah, I get it.
Sounds like they don’t even have the common sense to feel any shame.

How about you introduce that shame to them by practicing your very best “WTF is wrong with you” look and next time your face to face with them, shoot that look at their face and hold for a good long minute or two or just long enough to cause them to feel some awkward silence inside?

OK, I’m talking to you again. I will try to ignore them. I will consider that.

Ok good.
This is the Nick I know and love to talk to.

Basically me I have pride in not having pride and being one ugly ■■■■… on the inside.
