A: You look sad, what’s wrong?
B: Oh nothing, I can’t see to find my eraser at all, it was here just a minute ago.
A: Oh have you looked around?
B: I did, but no luck. I was doing my assignment, and I seemed to have made a little blunder here and there, I really need it.
A: Oh dear, I’ll help you look for it if you want.
B: That would be great, but for the time being do you have an eraser?
A: Yes I do! Do you want it?
B: I just want to borrow it, can I?
A: Of course you can.
