answer: Bob refuses a gift, an Egyptian carpet, sent by a student because although Bob is honored, he thinks it's too expansive to accept. He is worried that the student mistakes his refusal as a rejection of a bribe.
documents: #Person1#: Hi, Bob, everything okay?
  #Person2#: more or less. There's just one thing bothering me.
  #Person1#: oh? What's that?
  #Person2#: well, you know I have some students studying for their master's degree. One of them tried to give me a gift that kind made me uneasy.
  #Person1#: what gift?
  #Person2#: it's an Egyptian carpet. The student came to my office the other day and brought the carpet to show his gratitude. Seeing what gift was, I was really uncomfortable. I mean it's too expensive a gift
  #Person1#: you refused the gift? That's terrible.
  #Person2#: I know, but I really can't accept such an expensive gift. I explained to him why, but he seemed really upset about it. I think he might have taken it the wrong way.
  #Person1#: perhaps. He probably thinks you considered the gift a bribe for a higher grade.
  #Person2#: that's what I am worried about. I do understand the respect attached with the gift and I am honored. But I really don't think it's proper for a student to spend a fortune on a gift for a professor.
