"Single"

Although one is in color and another one is with no color, or one is living thing and another one is non-living thing, or one is up high in the sky and another one is down to the earth, or one can move freely and another one will stay there until a force had given, and all others differences that could been stated here but the reality is they are single. The most important thing that must be remember.. "single doesn't mean lonely" =D
