The past

I like walking always, because keep walking means I need keep my eyes focus on the future. And the future always change, it so mysterious, so attractive. I rest of my life to pursue the future.
But one day, on the way, I saw a man I never see. He was old, ugly and deading.
"Who are you?" I asked, and his dark eyes were lighted again immeditily.
"Oh, is you!"He was so excited.
"I am sorry, should I know you?"I am so confused and I stop my feet.
"Of course, I am you." He said and disappeared.
So many years gone, I arrived the end and I becomed a old man. But why? This place was what I begining, I went back, and I saw a young man who just like me, the young me.
"Who are you?"He asked.
"Oh, is you!"I was so excited.
"I know you?"He was confused just like me when I in that time.
"Of course, I am the future of you, I have arrived the end."I said, and I feel I was disappearing.
"What!"
"The death always the end of us, and the end is we can see the past of us, just it."I disappeared when I finished my words.
