There are many people on the bus. Some have seats, but some have to stand. At a bus stop, a woman gets on the bus. An old man sees her and tries to stand up.
"Oh, no, thank you. " the woman forces (强迫) him back to the seat. "Please don't do that. I can stand."
"But, Madam, let me…" says the man.
"I ask you to keep your seat." the woman says. She puts her hands on the old man's shoulders.
But the man still tries to stand up, "Madam, will you please let me…"
"Oh, no." says the woman. She again forces the man back.
At last, the old man shouts, "I want to get off the bus!"
