In my twenties I made spaghetti every Saturday night. This started as throwing some Ragu in a pot and adding some spices, and eventually morphed into crushing my own tomatoes and cooking over most of the day. I did this every week over years. A varied group of friends came to eat each week -- no plan, no notice, just come over if you have nothing else going on. It's how I met my wife -- I never would have had the courage to ask her out on a real date, but "I make spaghetti for my friends every Saturday, you should come over," was easier. It's been years and I don't often make spaghetti anymore.
