Why should you have a time capsule?

Time capsules are useful for capturing a good moment in your life i.e. to signify the end of childhood/adolescence. People may bury a few keepsakes, alongside notes or a diary, to be re-dug up at a much later date.

The pro of making a time capsule would be the rewarding memories which would come when you eventually dig it up! You'll be reminded of a part of your life which you'd probably have forgotten.
