Stephen Bishop said it in song: "Everybody needs love; from the old man sleeping in the corner, to the baby smiling in a hurricane."
Of course, one of the problems with life as we know it on Planet Earth is that some people tend to be a whole lot better at wanting things their way than in giving loving treatment to others. I would even go so far to say that we normally cut the Golden Rule in half. Instead of "Treat others as you would have them treat you, " we pretty much only concern ourselves with the being-treated-by-others part.
And because people are wanting others to treat them nicely...while failing to actually treat others nicely themselves...a lot of people are ending their days completely drained and in desperate need of love.
Take a look at this short video and tell me you wouldn't enjoy coming home to something like this every day.
Truth is...we can't all be dog-owners, but maybe we can work at being more dog-like.
