You can never own anybody.
You can only love people and hope that makes them so happy, or at least secure enough that they feel like you deserve, and that they can, love you back.
Hopefully they do. Hopefully, you get by. Hopefully people will care about your feelings. Even if you only feel like they do once in a while, you should have something in the back of your head, that makes you believe otherwise. You should remember you failed others too. And they forgave you, and fought for you, and loved you showing you you're worth it when you were afraid you were not.
What goes around, comes around. When you have a friend, it more certaintly means you are a friend. you need to be one to have one. And we don't deserve someone else's dedication 24-7, and we are not emotionally prepared to give it to others anyway. But it is in those hours of the day we somehow are capable to remminisce a time when others enlightened our days so well and bright, that we must take time to care about their feelings, their lives, their stress and their fears.
When you only care about a friend when you need someone to listen to your own life, you should probably take a second to think about the fact that you may be, if you haven't already,  losing a friend. A friend that will have your back if you may need it, but that will stop sharing his joys with you. Simply because you didn't show interest in their sorrows... You stop being cheriched and invited to the good times.
And if you think about it well enough one of the things about friendship is that you can open up your heart when it's completely smashed inside... And that feels just as comforting and ecstasying for pain as it does for happiness. There's a strange line of euphoria between those two. And you only realise you need to share it when you're about to step on it.

Which side am I sitting on?
