I don't understand people who say they are comfortable alone and I always assume that their definition of "alone" is very loose. I tend to get attached to people I want to call regularly, I want to know how they're doing, what they're up to, do they want to hang out, do they have anything to share? That's the definition of "friend", to me, and I don't have a single person in my life like that, and I haven't for about fifteen years. I don't get along with family either, so none of them count (for that standard). When people brag that they locked themselves in a room for a week, so they are qualified to journey to Mars now, that means I'm ready to commute to Andromeda, at this point.
