Girl: I' in a big trouble!

Boy: Why is that?

Girl: I saw a mouse in my house!

Boy: Oh, well, all you need to do is use a trap.

Girl: I don't have one.

Boy: Well then buy one.

Girl: Can't afford one.

Boy: I can give you mine if you want.

Girl: That sounds good.

Boy: All you need to do is to use some cheese in order to make the mouse come to trap.

Girl: I don't have any cheese.

Boy: Okay Then, take a piece of bread and put a bit of oil in it, and put it in the trap.

Girl: I don't have oil.

Boy: Well, then put only a small piece of bread.

Girl: I don't have bread.

Boy: THEN WHAT IS THE MOUSE DOING AT YOUR HOUSE?!
