Before I was old enough to date, my cousin would stay with us on nights she had a date. The first time some boy came to pick her up, he pulled into the driveway and honked the horn. When my cousin and her friend got up to go out, my Dad told them to keep their seat - in a rather impressive manner. (I had heard this tone several times before, usually with unpleasant results.

) My Dad then proceeded to go to the front door, open it, and proclaim loud enough for the entire neighborhood to hear, that if those two boys were man enough to ask out his niece, then they were certainly man enough to come to the door and meet her uncle and have a pleasant gentlemanly conversation. (The exact contents of this conversation, I was not privy to. However, I DO have my suspicions.)
I guess that stuck, because now I embarrass my wife whenever I go to pick her up anywhere. While other husbands just drive up and honk the horn, I walk up to the door and ring the bell. Oh well, that's what she gets for marrying an older man.

Nobody owes you anything.
