Here's a fun idea from the Ensign magazine, published by the Church of Jesus Christ of Latter-day Saints. Don't you wish your deceased family members had kept some sort of journal? I know I do.
Connie Pope, “Family Stories,” Ensign, Apr. 2009, p. 71
When our children were at home, we made history every week — our own family’s history. It was a tradition my parents started when I was young. We simply set aside 10 minutes together to write on an assigned topic. When finished, we shared what we had written down. Some of the entries included telling about a Fourth of July (or a Christmas, Halloween, or Easter) we remembered, describing a grandparent, telling about an accident or illness, or recalling a vacation or fun birthday tradition.
When we were done, each of us had a binder to store our growing collection of journal entries. We enjoyed sharing each other’s experiences in this way and are grateful that we preserved special memories.
