The recipe

Start with working out, putting on some makeup, add flirting and then entering into a relationship. Date a while and challenge each other until you are sure they won't run. Move in together and show a little more about who you really are. Have some great sex and decide you want this forever, get married. Add a mortgage and a shared car. Get pregnant a few times, maybe add a pet or two. Have some babies, enjoy them to teenagers, make sure they move out safely and securely and then go back to flirting and dating.
