Pizza is how we get out of mealtime jams created by their busy lives. Pizza is how we make a shopping trip special when the purchases will not be for them. Pizza lubricates the social life of adults, too. You can serve your guests any fancy meal you want because you can always order pizza for the kids. Order pizza for the kids.
Pizza is our excuse to get together as a family.
Even teens will agree to be seen with their parents in public if the family is going out for pizza. Dinner out with the family isn't ruinously expensive, because you are only having pizza. And you can usually get a beer in a pizza joint. You can teach your children to cook using pizza. This skill, more than staying home without a sitter, makes them feel all grown-up and independent.
