A short anecdote: "Sometimes Children Are Better Than Adults"

[infiniteone]

When I turned my head, reading some books in a libraray, I saw a girl-maybe 5 to 7 years old -and a lady who looked like her mother, choosing books to read, in front of the bookshelf beside the table at which I was reading. And the moment I was about to get my eyes back to the book, I heard a "Hello" sound, a female's phone voice. It was her, the lady who looked like the little girl's mom.
Yes, she was speaking on her cell phone. But, I wasn't suprised that much because she was not the only person who phones in the library reading room. So I just decided to go back to my work. I was about to read my books again, and then at the moment, I saw the little girl jittering, embarassed by her mom's acting. She scolded her mother and the mother got her voice down. Of course, I had not expected that she would go out to keep her phoning.
It was a role-diversion. The daughter did the mom's role, and the mom acted like a little naughty child. Sometimes Children are better than adults.

When I turned my head, while reading some books in a libraray library, I saw a girl-maybe 5 to 7 years old, and a lady who looked like her mother, choosing books to read, in front of the bookshelf beside the table at which I was reading.
It might be better if you broke this long sentence into shorter ones. This type of construction tends to be tiresome to read.
"When I turned my head, while I was reading some books in a library, I saw a girl, maybe five to seven years old. Next to her was a lady who looked like she was the girl's mother. The lady was choosing books to read from the bookshelf beside the table at which I was reading."


And the moment As I was about to get my eyes back to the my book, I heard a "Hello" sound, a female's phone voice. It was her, the lady who looked like the little girl's mom.
I'm unsure if you mean that the lady looked the same as the girl's mother or she was the girl's mother. A green Ford looks like a green Mercury, but they are not the same car.

Yes, she was speaking on her cell phone. But, I wasn't suprised that much because she was not the only person who phones in the library reading room. So I just decided to go back to my work. I was about to read my books again, and then at the moment, I saw the little girl jittering, embarassed by her mom's acting mother's actions. She scolded her mother and the mother got her lowered her voice down. Of course, I had not expected that she would go outside to keep her phoning continue her telephone call.
It was a role-diversion. The daughter did the mom's role, and the mom acted like a little naughty child. Sometimes children are better than adults.

Your writing is fairly good. You do tend to put too much into a sentence - they are too long. Read the sentence. If you have to stop to take a breath, the sentence is too long.

This is not an essay - it is an a short story or a verbal picture of an event.
