Now whenever I hear of a friend who's lost a loved one, I no longer call with the polite offer, "If there's anything I can do…" Instead I try to think of one specific task that suits that man's need, like taking the dog to the boarding kennel, or house sitting during the funeral.

Call the implemented task.

Usually, SCA clients call human task components using an SCA wire, that is, they are statically bound to the corresponding tasks.
