I had dinner with someone once and was worried about not knowing them very well and that awkward silence. A few days before, I gathered up some pictures of my children when they were younger and now, some of our river cottage and some of the trips we had been on. When the awkward silence happened, I pulled out the little album I had put them in and started to show the pics. This created conversation and allowed the other person a chance to brag about their children/grandchildren, trips, or whatever. I would suggest maybe getting some pics together of you and your family. Any family pets you might have had. Your first day of First Grade picture. Parents like this kind of thing and it shows you are close to your parents and your family. It also shows a respect factor and perhaps they will feel that you are respectful enough to be dating their daughter. Stay away from talking about politics, religion, and race.
