I have read a book about shyness for three days.
And this morning I finished reading this book.
This book is very helpful for me!
Because I don't think I am shy, but I am shy.
While I was reading this book, I felt stressed many times.
But I knew more about myself, I want to change my behavior to others.
Thanks to my friend.
He presented me this book.
He is the best friend of mine.
