One of the great joys and benefits of ageing is the possibility of being in very long-term friendships – such friendships, by their very nature, are not available to the young. These friendships ground strong reciprocal special obligations. Such long-term friends have very strong obligations to care for each other as they age and as they become vulnerable as a result of declining mental and/or physical strength. These long-standing intimate relationships, insofar as they ground strong special obligations, are precisely what a friend ought to be thinking about as she is moved to care for her friend. Thus, in thinking about a duty, one is thereby thinking about the valuable relationship that has bound one to one’s friend over an important and extended portion of one’s life. Acting from a special obligation to a long-term friend is to act in precisely the right sort of caring way.
