If we are observer we would have noticed two kind of loners. Those who wear their loneliness comfortably. At ease with themselves, their gaze is steady and introspective(self examining). Friendly if someone approaches them they aren't unduly perturbed( disturb in mind)
The second kind of people are those extremely uncomfortable with their loner status. They are awkward if someone talks to them, and more so when ignored. Bad social manners yes, but beyond that, you can figure these are lonely people who haven't learnt to be comfortable with their aloneness.
Loneliness is not the same as aloneness. Being alone implies not having anybody with you : it's a state of being. A person who is aline my or may bot lonely. You can be comfortable and positive with you aloneness, or you may choose to be negative about it, which is when becomes loneliness- a state or mind.
Loneliness, if fact, doesn't just strike those who are alone. It can strike you even when you are in the midst of a crowd. You don't have to be alone to be lonely! Sitting amongst friends or even with family, one be lonely. One can sometimes feel a searing loneliness that is inexplicable. This can get quite disturbing since there is no plausible cause for the feeling of isolation and depression.
