Give people the benefit of the doubt

The person acting rudely may not understand the culture or "The way we do things around here" and not realize they are being rude.

Give people the benefit of the doubt. Instead of getting upset with someone for cutting you off in line or communicating poorly at work, try saying:

“Excuse me, you may not have realized, but I’m already in line here.”

“I would be happy to help show you the ropes on this project. It seems like it’s making you a bit stressed out.”
