When one of the ones I know well comes to visit for a (non working) vacation, this is one of the conversation topics that often comes up: she reflects on how much longer she will work, the pluses and minuses. It often digressed into these topics.
They use different words, but the ones who have survived in the business all compartmentalize it. Just like guys I know in other jobs they really would rather not be doing, from offices to manual labor to some sleazy work of different types. They compartmentalize the work as almost a different reality, different person, from the rest of their life and in many ways try to forget it (or at least not think about it) when off work.
Most say they have a few clients they like and enjoy--the ones who treat them like "a real person", be it a friend or just a really good lover. They have had some men who they despised, the ones who act as if she should be grateful that they see her. But most are work--emotionally nothing, neither good nor bad.
