Why go out?

For many years ive asked myself,why do you spend time with other people?but never really attempted to come up with an answer .I always believed I was asking myself a rhetorical question but recently ive wanted to find an answer,because a question you ask yourself a thousand times eventually deserves to be answered. I figure if iknow why I go out ,I might feel less suspicious of myself for going out .I might criticize myself less.Imight be able to look around a party without thinking .what a fool?why did you come ?you should have stayed at home .
