An individual who enjoys spending
time alone just as much as spending
time with people; however, he or she is quickly worn out by large crowds and must withdraw from people for a while in order to balance themselves out yet again. These individuals are naturally quiet, inconsistent, and very easily
bored.
A "social
loner" will sit in a room alone for hours on
end, and will comfortably be more entertained than if they were at a social event, but only because intelligent people are a rarity these days, and all others a waste of
time.
