From Clarissa’s blog:

Sociability is difficult not because it’s hard to socialize but because I never know if my sociability switch will turn on at any given time. When I approach people or people approach me, there are two possible scenarios:

1. Sociability switch flips, and I become the most charming, gregarious, exciting person ever.
2. Sociability switch decides to remain inactive and I feel intolerable boredom. I can try to conceal it but the boredom is overwhelming.

The bad part is that I can’t predict when each scenario will unfold. I don’t suffer from not knowing how to engage with people or how to make small talk. I’m actually great at it because I don’t understand the concept of worrying what people think about me. What I do suffer from is frequent and uncontrollable attacks of not wanting to engage.

It feels very weird when in the middle of a conversation I lose all interest and become extremely bored but not because of anything the other person said or did.

It’s equally disturbing when I open my mouth and all of a sudden this very charming, talkative persona appears.
