Caring about someone or for someone can be rather ambiguous.

When I was a teen, I once said to a person... you dont care do you (in relation to me).... and they said that they cared what the weather was going to be like tomorrow.....ouch..

Caring means different things to different people. Im sure some therapists care about their clients in a simar fashion as a dentist cares for their clients. Out of sight out of mind...
