It is important for a couple to have rituals. Rituals allow us to carve out space and time that is special, separate from ordinary time. They connect us to the past and to each other.
SH and I have many rituals. One is that he asks me why I do something, even though I have no answer. Another is that he straightens the knife rack. He also keeps the toothpaste squeezed properly.
Then there is the ritual where he cuts coupons for products we do not really need and sticks them on the refrigerator, where they stay until I go through them and throw out all the expired ones.
