Family is everything. Remembering together good old days brings great joy. Perhaps this needs to be a regular exercise. Periodically, but spontaneously looking back together and enjoying the great moments we had together is not only joyful but gives new perspective to the current happenings in life.
Many unutilized resources such as gifts, photos, videos etc can be of great help, but more than all this is going down the memory lane together will always prove to be a priceless experience.
