In his grief over the loss of a dog, a little boy stands for the first time on tiptoe, peering into the rueful morrow of manhood. After this most inconsolable of sorrows there is nothing life can do to him that he will not be able somehow to bear. - James Thurber
Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable. - Sydney Smith
