Disappoint

If, as correctly assumed, the natural state of the present author is one in which disappointment is elicited such that acquaintances and family are frequently let down, it stands to reason that, while having no social network or friendships may be damaging, it also prevents a propensity of disappointment that would be demonstrated regularly by such friendships. That is to say, you can only disappoint so many people, when you only know so many people to disappoint.
