It's frustrating when someone cancels dinner at the last minute.
Samantha is planning a huge dinner celebration for her recent retirement, and she invited Rudy to it.
Rudy needs to cancel showing up because of a work engagement that same day.
Rudy tells Sam the moment he receives the invitation that he has a work obligation and HAS to go.
Rudy calls Samantha the day of and fake coughs into the phone saying he's ill and can't make it, because he's afraid to tell her the truth.
Samantha understands, she's hurt but doesn't think less of Rudy for it.
Samantha doesn't believe Rudy and is hurt that her friend would lie to her.
