there was a bookseller.he did not like to pay for anything.one day a big box of book fell on his foot.
go on the doctor,said his wife.and show that foot to him.
No,he said.I'll wait until the doctor comes to our shop next time.then I'll ask him about my foot.If I go to see him,I shall have to pay.
the next day the doctor really came.he looked at it and promised to help.
he took out a piece of paper and wrote something on it.buy this medicine and put it on the foot before you go to bed every night,he said.
thank you ,said the bookseller,and now,sir,there are your books.
how much?asked the doctor.
two pounds.oh,good,said the doctor.I shall not have to pay you anything today.
why? asked the bookseller.
I looked over your foot.I want two pounds for that.If people come to my house,I ask them to pay only one pound for a small thing like that.but when I go to their houses,I usually charge two pounds.and I came here today,didin't I?
