    Life is colorful. Sometimes it's just like potato salad; when it's shared it becomes a picnic.

    With three young children, my husband John and I were very 1. “Can we go on a picnic, Mom?” my six-year-old daughter, Becky 2. “Please.” I had said no so many times in 3 months, and I decided the usual Saturday morning chores could 4. To her 5, I agreed.

    I prepared a few sandwiches and 6 a cooler with ice and drinks and called John 7. My eleven-year-old twin sons loaded the cooler and the picnic basket in the trunk and off we went to spend some 8 time together as a family.

    About the time I got the lunch 9 out on the table, John arrived on the 10.That was one of the happiest meals we ever shared together. The meal was filled with 11. We felt a closeness that had been hidden by work and school responsibilities for so many months. John and the boys 12 rocks into the lake. Becky fed the ducks and I sat quietly on the picnic table, 13 God for blessing me with such a wonderful family.

    That night as our children went to bed, I kissed their cheeks and 14 what a wonderful life I had. As I walked out of the room it dawned on me that even the busiest 15 could become a picnic when it's shared with the ones you 16. Even though the kids have now grown up and 17 from home, I can still remember how I felt that day while sitting at the picnic table.

    Maybe today would be a good time to 18 potato salad, call all of my 19 kids, feed some hungry ducks and skipped a few rocks into the lake. Since life is like potato salad, let's make it a 20.
