MUST REMEMBER THIS . . .
It's true, people are not what they seem on the outside. A person's facial expression, her tone of voice, the amount of sleep she had the night before, can colour so much. But none of these things speak her heart and soul.
I make many assumptions about people -- ironically, usually about people I don't know very well. In contrast, it's the friends closest to me -- the ones I know the best and whose inner thoughts I probably could accurately plumb -- whom I afford the greatest caution. I could safely make assumptions about them and their thoughts, but I don't; I am more wary to not step on their toes and to not delve into them too deeply or sharply. I see now that I've got it backwards.
Instead, I should exercise safety in abandon with these closest and dearest. Assume the best from them and allow the same. And the space and grace that I afford to them now, I should instead focus onto those I have yet to warm to.
