Time Gose by so Fast

Today, I take took my nephew to go to a little park which is near his house. He is gets happy when he plays is playing in the park. (He enjoys playing in the park.) Now, he is four years old.

I saw how little he was when he was born out. At that time, he was not able to speak, not able to walk and more not able to or run. But now, he has grown up now and he can speak and his has good ability of language expressing himself/his thoughts is better ton than his contemporary children. And He can walk, and he can run and he can even jump too.

Today, I watched him playing in the little park. He was singing songs while he was walking and running so freely in the park. I thought I do not need to worry now that he will fall down. Seeing him, I heaved a deep sigh. cannot but say a sigh that Time goes by so fast, doesn't it?
