There's a good passivity in life, one you learn to exercise with time. If people want you in their life, after you've shown and done your part, they will make it clear to you. Simplicity is always an active positive ingredient in human relationships.
Sometimes you meet someone, and before you know their name, before you even know where they are from, you just get the feeling that sometime in the future this person is going to mean something to you.
I have to remember this. I have a tendency to want to hold on to people forever. And when they don't want the same, I become hurt, and react by building walls. I am grateful for the time some people gave me.
