Advice

Dodi had a problem. He went to Didi, his work mate, to discuss the solution.
Dodi : " I am so confused right now. I must decide whether I choose Rina or Hana. You know, Rina is         prettier, but Hana is richer."
Didi : " Don't be confused! It's simple problem. Just choose Rina. She is more pretty and more smart than     Hana, isn't she?"
Dodi : " Hmmm....I think I agree with you. Thanks Didi for your advice."
Didi : " You are welcome. But.....by the way, can you tell me Hana's address?"
Dodi : ????? What for?
