I am not saying they may not be human - perhaps they are, but the exchange of money for their time and focus on the client is the bargain. It is not particularly natural, but there it is. They set it up like that. The client does not take care of the therapist. The client PAYS the therapist. I am not saying go out of your way to be rude or mean, just stop worrying about them and give them credit for being able to take care (or get care) of themselves.

If someone wants closure for themselves, then have at it. Just not for the therapist.
