Would this reaction be rude?
Bob and Jane see each other twice a year. Everytime Bob asks Jane how she's doing, she gently answers, "Fine." He makes fun of her answer each time which eventually annoys her. To prevent him from doing that, she tries replying once, "Fine thanks. And you?" As a result, Bob says that he's doing great. The next time they see each other, Bob asks Jane how she is; she answers, "Good." Then he blatantly lets out a giant "PFFT!" while raising his arms & quickly putting them back down. Was that reaction of Bob's rude?
