I don't think your reaction means you don't care. Good lord - just because a client does not like their time being interrupted and paid for time the therapist spent on something else means that client is a bad person. It does not matter what the other thing is - the client gets to have their feelings (even if someone else deems them the wrong ones) and gets to tell the therapist about it. Therapy is the place one gets to have and express feelings that are not the nice ones.
