Only For A Moment

You know it is amazing how nothing stays the same for very long. This cloud which kinda looks like a bird, changed a moment after I took the picture. It is gone forever. When I was in school it seemed like I would be in school for a hundred years. Then when my kids were going to school it seemed like they would be there forever. Now that is all gone and I am in another moment and I am sure it will also be gone soon. What the heck are we doing here anyway?
