My husband and I have begun praying the Liturgy of the Hours together. We pray morning prayer on our own, but night prayer we pray together.
If you are interested in praying the Liturgy of the Hours, especially during Advent, here are two on-line resources to get you started:
Selected prayers at E-Breviary. If you want the entire set of prayers, you must get a subscription.
iPhone apps, podcasts, and more at Divine Office - Liturgy of the Hours.
