A friend asked me what the worst feeling in the world is. I told her it was regret. Regret is one feeling I didn't experience a lot but I'm pretty sure it's the worst feeling ever for me.
She told me hers was loneliness, another feeling I haven't experienced a lot, because I always found ways out of loneliness. When I was alone, I was happy with it being a choice. I knew how to do things alone, to walk downtown alone, to smoke in a cafe alone. And it was good.
The worst loneliness is loneliness with people being there to actually witness it, and not making it any less.
The opposite would, naturally, be good company. And one you have that, it makes you warm for the whole winter season. Friends that you consider family, a partner that you can always be comfortably silent with. Once you have these, you know you'll survive.
You know you will have lost the energy to do things alone, but you know that you have better company than yourself.
