Life Story, an image about a school

This is a school group photograph taken in Harlem, USA in 1958. The same people stood under the repeated picture in 1996 where they stood in 1958. Most people have passed. And when the picture takes place, their places were left empty.
These 2 pictures are written down:
(1) Life is temporary. Your God can call you back at any time.
(2) The position you hold today is not permanent. You will empty it one day.
(3) There is no room for hate and greed in life. We must be value and love each other.
(4) In 50 years, most of us have left behind all our efforts and hard work. This life is very short for hate and greed.
Love and appreciate each other
It’s not with us forever. Whatever happens in the present moment is the best moment.
