After introducing herself, the therapist then asked the patient if it would be all right to do the exercises which the doctor had ordered for her. The patient would response, "Well, I don't care to." For several days, the therapist immediately left the room and officially recorded that the patient had "refused" therapy. […] It was not until months later that this therapist […] discovered that she should have been interpreting "I don't care to" as "I don't mind" doing those exercises now.
The sense "to want" is most commonly found as an interrogative or negative sentence, and may take a for clause (would you care for some tea?) or (as a catenative verb) takes a to infinitive (would you care to go with me?). See Appendix:English catenative verbs.
