A Very Sad Act Of Silliness

There was a couple in India who terminated their own physical existance after their dog, Puppy, who was 13 years old departed his physical body. I'm sorry but I just don't understand why humans doo such silly things. Everything else in the natural world struggles to survive at all cost but humans sometimes destroy themselves. It's really rediculous. I'm sure they loved Puppy but he probably wouldn't have wanted them to harm themselves. Perhaps they thought of him as a child since they didn't have any human children. Sometimes humans do things that are so strange only they understand them I suppose.
