Similar vibe, but I think about this scene/meme a lot as well.

Likewise, Don Draper is being an asshole in the scene. But, in reality most people don't think about you.

They could say something that offended you. They are going to forget about it. So there is no need to be upset, chances are they forgot about it.

You could say something dumb or embarrassing. People are going to forget almost immediately.
