I went to school and learned a lesson. We often hope that our children learn from these lessons, but sometimes the lesson learned was not the one intended.

This could be called a useful piece of practical wisdom, and for me that was, don’t get into fights at the back of the schoolyard.

The former lesson can be, on one hand, a section of school work, from a larger continuous topic, or, part of a book, which can be an exercise.

Then there’s the study of the past and the hope that we can learn from the lessons of the past.

Sadly, in a lot of cases, we don’t and are therefore doomed to repeat the past, only with far more devastating consequences.

A lesson can also be a passage from the bible.

Or is it lessen, where we reduce the costs which means lessen means reduce, to make less.

I could lessen the load if I gave someone else some of the work.

Or if I stopped eating candy, I could lessen the chances of clotting arteries.

No, I don’t think I will, just have less.
