I’m sure most of us have done this as a kid, or recently if you are a kid. Buried something so you could dig it up later, like a special treasure. Unless you forgot about it, it usually would not be long until you dug it up to rediscover things from your… “past”. As an adult this is something I inadvertently do, but it can be just as enjoyable. When you stuff some keepsakes in an old box in storage, or something gets scooted under a bed or stuck somewhere in a junk drawer. Then you find it some time in the future, and relive a few memories briefly in your head. Good times.
