Why?
How can it be?
These are such simple questions that anyone can ask, yet, sometimes they provide difficult answers.
I'm sure at some point you've come across a curious (annoying perchance?) child. If so, then you already know how difficult why can be.
At some point you have to draw the line and say "I really haven't got a clue"
No one has all the answers
Anyone that claims they do is not speaking the truth.
And how? Who would know?
The chicken or the egg? How?
A million answers to every question.
Who am I to tell you which one is correct?
