Do you have any rituals?

Is there something special that you do once a month, once a week, possibly even every day?  For example, every Sunday evening I go to get Indian buffet with my best girl friend.  She and I eat together and then sometimes we go to get coffee at a cafe afterwards and read books and chat, catching up on our week's news.  I look forward to it every week because it is a nice Sunday with my friend, whom I don't see so often.  What is your ritual?
