. . . .

Why are you walking like this?

Because you are sometimes mean to me.

Take it easy...

Do you want to hear about a moral dilemma?

Uh-huh.

OK. Imagine a tram going towards five cats sitting on its tracks.

Oh dear...

You are at the switch and you can divert the tram to another track, where there is only one cat. Would you divert the tram to save five cats and sacrifice one?

I think...

... I am going...

... to bed.

Good night!

What is wrong with you? I think it is cool problem.
