How to astound your girlfriend's parents

Well, you're going to marry but still don't know her parents. But you must do it anyway. The sooner the better.

1. Forget all of the dirty words that you know. It's difficult but you must. Keep in your mind several Latin sayings and pronounce it in the hottest moments.
Warning:
If they don't know Latin, you'll risk to be looking like guy-who-knows-very-dirty-words.

2. Dress as if you're going to visit the royal family but don't overdo. Let them think that you're not a prince but aspiring to reach a high position in society.
Warning:
Leave your T-shirt with description "Linux is forever" at home.

3. Try to avoid the questions about your relatives who are not worthy of good references. Tell them only about your forty-second cousin who works in the White House but don't go into details about his great ability to shear lawns virtuously.

4. If they ask whether you have some vicious habits or no, tell them that you don't smoke anymore. No one of them will know that you'll start smoking in two hours.

5. Ask about their daughter, and the more the better. Parents adore boasting of beloved offspring, especially if aren't sure of their beauty or cleverness.

6. Be holding your girlfriend's hand, showing your love and looking like a spooney. Tell them how you imagine future life with their daughter - five kids and small house outside of city.
Warning
Get ready to know some hot details about your intellect from your girlfriend after this meeting.
