In your life, what events have you found difficult to explain?

There’s a lot about life that is difficult to understand. They are even more difficult to explain to someone else—be it a child or an adult. Things like war and death and life and where we came from and why we are here are huge topics that people struggle with.

I want to go further then those huge topics. I want to make it personal. What, in your life, have you found difficult to explain? Why is it so difficult.
