It doesn't matter how well you are (or are not) getting along with your family right now: you need to get in touch with one or two older relatives you haven't seen in a while. One simple phone call or short letter will have a gigantic effect on their lives, and it will require only minutes of your time. Thinking about your past will remind you of funny stories that need to be shared with the people who helped create them. Reach out and start sharing.
