Mother: I refuse to believe that someone who came out of my own womb could possibly think that Jeremy Corbyn could be prime minister.

Son: When you were my age, you’d have voted for Corbyn.

Mother: I would NOT!

Son: Yes, you would. You were far-Left then, and now you’re far-Right.

Mother: Excuse me, young man, I am not far-Right. I am in the centre. I voted for Tony Blair. It’s Corbyn who’s extreme.

Son: We need change. Corbyn promises change. Young people can see that. The system’s broken, obviously.
