I'm not going to be on time. Everyone will think I'm being deliberately late in order to emphasize my own importance by making them late.

When it comes to a thought like that, I would ask: "How bad would it be if other people think that I'm to late to emphasize my own importance?"

How much negative utility would be created? How much money would I pay to prevent that this effect happens?

Hmm, this guy isn't responding to my text. Maybe he could have come to the conclusion that I'm a vicious racist!

If a person thinks that I'm a vicious racist based on what I say, than that person is crazy and we aren't a good match. I would rather spend my time with other people so it's no problem that the guy isn't texting me.
