When the kids were little, we tried to have our "couch" time, which basically was about 10-15 minutes each evening when David would get home from work, and we could sit and talk. The kids knew this was Mommy and Daddy's special time that was not to be interrupted. It helped us not only connect with each other on a sort-of regular basis, but it helped establish the priority of the husband/wife relationship in the children's eyes.
With our tremendously busy schedules today, setting aside time to just sit and talk is quite difficult. So many times we drag ourselves to bed and just starting talking only to fall asleep mid-conversation. There are many evenings when David is working late, or when we're running in different directions getting kids to Bible Study, swim practice, or to some other event.
Fortunately, we have found a solution for this season of our lives. On Sunday mornings, David and I meet at the Starbucks down the street from our church and have breakfast together. It's 30-45 minutes of just "us" time. It's not unusual to run into a friend and chat with them, too, but it's our time to relax, reconnect, and just look at one another. Soon enough we run off to the morning service, but for now, this is our special time just for us.
