— May I borrow your pen?

— +Do. Do you want a black one or a blue one?

— Which one shall I choose?

— It’s up to you. You must make up your own mind.

— I can’t draw a line.

— Well borrow a ruler.

— Whose?

— Dasha’s.

— Well give up the idea. I borrowed her ruler two weeks ago and I lost it somewhere.

— You must pay for it.

— How?

— Think of something, you helpless man.

— Maybe I should buy her another ruler or a bar of chocolate instead.

 

— Clever, aren’t you?
