Where, Why, What, When and How (3)

......... did you say to him? He's very upset!
......... on Earth could you afford to buy that mansion in such a beautiful neighborhood? I thought we made the same amount of money and I can't afford anything like that.
That will be $50. ......... would you like to pay for this? We take cash, Visa or Mastercard?
I don't understand ......... you see in him. He's rude and he is not nice to you at all.
I don't know ......... you think you are going! You are grounded and you're not allowed to leave this house for one week.
Can you help me look for my keys? I don't know ......... I did with them.
......... on Earth is this all about? I left for two hours and now you're really upset. Did something happen while I was gone?
......... happened? You look very depressed. Is everything OK?
......... are you going to come home? I miss you! I hope to see you soon.
Can you tell me ......... the post office is located? I've been walking around for an hour and I can't find it.
