solitary, sentenced, alone
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.
The capacity for not feeling lonely can carry a very real price, that of feeling nothing at all.

Absolutely lonely people have few personal interactions of any kind.
ALONE, INTERACTIONS OF ANY KIND
Yes, I guess you could say I am a loner, but I feel more lonely in a crowed room with boring people than I feel on my own.
