Linda, a radical feminist, was getting on a bus to go to work.
As she walked down the aisle to find a seat a man just in front of her got up.
Linda thought to herself. 'Here's another man trying to keep up the customs of a male-dominated society by offering a poor defenceless woman his seat,' and so she pushed him back on to the seat.
A few minutes later, the man tried to get up again.
Linda was further insulted and refused to let him up.
Finally, the flabbergasted man said, 'Look, you've got to let me get up. I'm two miles past my stop already!'
