I m almost that gray-haired old man

I'm almost that gray-haired old man on the bench, stopping once at which, as a boy, I thought, will I ever be like this.
Now most of my life has been lived. And the main thing that I realized is to be grateful to the Creator. And thank Him for all this life experience, which is modeled for you by providence and by the assumption of Heaven.
And be grateful that you have lived to this day. Also, and for this moment, when you can contemplate this touching seasonal performance, with bright colorful scenery, which the next autumn plays out in front of you on the streets and parks of the city.
And each coming autumn is more and more disturbing to the soul.
And the familiar music sounds somehow special at this time.
And you don't regret anything anymore.
And you value only what is really valuable and expensive. 
And everything else is just leaves that will be blown away by the wind and turn into dust.
