I learned carrying address and phone numbers when my father was going to daytime adult care in our home city and one day just wanted to go home so he sneakily slipped out without notice and then got lost on what he thought was the way home. A nice young man found him wandering looked in his wallet and brought him to his home where they called us because we had our number but not our home address (don’t ask why, but we never dreamed this would happen)! 25 years later, I will never forget that experience and how thankful I was that there was a nice young man sent by an angel to guard my dad!
