Findng joy in saddness

My "full-time", paid, job I work as a libraian in an elementary school, the 2nd paying job is as an office assistant in a funeral home.  I have only been working in the funeral home for 6 months, my daily office duities are becoming easier.  But the saddness that I feel for a family when they come in to make arrangements for their loved one I hope never fades.  1) because it ensures that I am still a human with a heart  and 2) it keeps me humble.  I find happiness and greatfulness in their sorrow, it reminds me how precious our time is .  We are not guaranteed tomorrow and I treasure my time with the ones that I love so much more. I also find that I try to live my life a little more fuller than I had in the past.
