(I am not a teacher and this is my first entry to correct so forgive me if it is confusing.)

I saw a cute children (Children's) book at a bookstore last week when I met my friend.
The place where I met my friend was kind of a complex mall so there are many different stores, like a shopping mall with combined shopping units, and so on..
We had lunch together then we went to the bookstore. strolled the mall and found the bookstore. It was a pretty huge store!
My friend and I have an interest in English books so we went forward to the “traveling abroad” section of the store. We sat down and looked at the interesting book until my friend found one book which was obviously children's book because of the huge cute pictures. It was about a story of a Elephant and his friends. There is a series for this book and if I were a child, I would get the whole series!
