b_tterness of life, a matter of i and e

The bitterness of life must be the fossils of the remains under the deep soil.
As the years pass, the remains sulk deeper until no one can observe it from above.

But when an archaeologist finds it,
the fossil must be used again in such a way that it won't bring back the bitter taste of the past,
however,
it will be used as a display in the museum of experiences that will showcase the learnings from it and will leave a captivating smile to those visitors making them ready when history repeats itself.

Thus,
the bitterness of life from the past,
should be the "betterness" of life for the future.
