One day when I was on a bus, two old men -- one standing and the other sitting --- began quarreling over a seat, even though the bus still had some empty spots. The passengers frowned at the men's behavior, but their voices kept getting louder, and echoed throughout the bus. So we had no choice but to listen to their argument.
A(standing): No, thank you.
B(sitting): I'll give you my seat.
A: No, again.
A: Because I don't want it.
B: How old are you?
B: Then you should take this seat!! I'm still 82!
It turned out to be a very funny quarrel, and everyone started to giggle.
