They are rare as precious stones and far more valuable. In the past year there has been seven student deaths on my campus. Three of the students I knew personally. One lived on my dorm floor, the second I had several classes with, and the third I always hung out with.
I’m so sad to see them pass away. They were well loved and will be greatly missed by everyone. I am always stunned that Friendships can be stronger than the vast distances that can some time arise but then they are so fragile. At least in this life ;)
Tell your friends and loved ones that you care for them.
