Who was the thief?

 People are not so honest as they once were. The temptation1 to steal is greater than ever before -- especially in large shops. A detective recently watched a well-dressed woman who always went into a large store on Monday mornings. One Monday, there were fewer people in the shop than usual when the woman came in, so it was easier for the detective to watch her. The woman first bought a few small articles. After a little time, she chose one of the most expensive dresses in the shop and handed it to an assistant who wrapped3 it up for her as quickly as possible. Then the woman simply took the parcel4 and walked out of the shop without paying. When she was arrested, the detective found out that the shop assistant was her daughter. The girl 'gave' her mother a free dress once a week!
