One possible view of "the loner":
The loner might be such as he or she does not have the confidence to mix in the usual social circles.
They might be loners because they only care about themselves and to give time to others is wasted effort - by their view of things, ( narsissists ).
They might be such because they are painfully shy.
They might be such because they feel that others don't understand them.
One thing is sure; if they remain loners they are going to get identified by others as freaky and strange and they are going to suffer because of their insularity.
When they go into real-life they are going to be expected to be able to make social intercourse and if they cannot mix they will be ostracised from normal society.
Most modern workplaces are engineered around the teamsmanship or the group ethic and if they are not able to function in a group they are going to suffer again from this flaw.
( There is no "I" in the word "Team" )....they say !
Being a loner as a youngster is a luxury that you can get away with but once you are in the mainstream of society this luxury then becomes too expensive to maintain.
