The condition of being unfriendly or not wanting to socialize with others.

Unsociableness → It is formed from "un-" (meaning not), "sociable" (from Latin "sociabilis", meaning able to be allied or social), and "-ness" (meaning the state of being). The word describes the state of not being sociable or friendly.
Think of 'not' ('un-') being 'social' ('sociable') — that's why unsociableness means the state of not being friendly.
