You know how old you are, but it's just a number. Your life continues with your routine and although years are going by, the reality of it also becomes routine and you don't feel it's really happening. Like the slow process of gaining weight, you see it everyday and don't really notice it. But it's very obvious to someone who hasn't seen you in a few years. I guess the aging process can be ignored also. It's not that we don't realize we are older, but we are detached somewhat from the tangibility, the actuality, the perceptibility. Until we get this in the mail. Like a slap in the face with a cold wet rag.
