[hinkley]

Boring, difficult, or terrifying.

One of the groups that wash out of meditation immediately are those who it turns out are afraid of being alone with their own thoughts. These could be dark thoughts, or they could just be the sort of person who always fills the silence in a conversation (for that reason or a myriad of others).

I went on a long trip with someone who thought I wouldn't make it 3 days without the internet. Turned out they were the one who needed the fix on day 3. You can't really see what's going on in someone else's head so you don't know how they will react to having to entertain themselves without props, until they do it.
