lonely, alone, company
If it's true that our species is alone in the universe, then I'd have to say the universe aimed rather low and settled for very little.
The best part about being alone is that you really don't have to answer to anybody. You do what you want.
It's often just enough to be with someone. I don't need to touch them. Not even talk. A feeling passes between you both. You're not alone.
I love to be alone. I never found the companion that was so companionable as solitude.
I finally faced the fact that it isn't a crime not having friends. Being alone means you have fewer problems.
