If we aren't sure and don't know absolutely the how and why and where and when of a life happening, let's call it for what it is, and admit that we don't know. And if we are meant to, we will, and if we are not, we won't. Some things become clear as they unfold, or else we understand them in hindsight, and some things aren't ever going to make logical sense to us. They simply are what they are, and that's the most we will ever get.
Knowing how easily I misconstrue situations, and people, I am willing to make room in my thinking for the fact that I may not understand the real reality.
