Its not what you know, its who you know. You could know.. life sucks and your in it alone, and be in the darkest mood; and then get a random gift of kindness from the people you've thought forgotten about you.
People surprise me.
You, yourself of all people, wanders in the mind of someone else, somewhere. As much as you like to think how impossible that sounds, sooner or later you have to realize, its not. Someone's been thinking of you, and it matters. Drop whatever image or idea you have about people not caring, because somewhere, someone is. Even if its just one.
