All my life I have loved periods and moments of sadness. It seemed to me to be a noble emotion, both hurtful and sweet. However, I'm not quite sure where it fits in the belief of eternal personal recurrence . . . because . . . you never really say "goodbye" to your loved ones, you say, "see you in 30 years" or just "see you soon".
Perhaps animals are right. They never cry. Their periods of mourning seem very short or not there at all.
