Cách sử dụng
The expression "read somebody like a book" means that you can easily understand what someone is thinking or feeling just by looking at their body language or behavior. You can use this expression when you feel like you know someone very well and can predict how they will act or feel in different situations. For example, if you notice that your friend is fidgeting and avoiding eye contact, you might say "I can read you like a book, you're nervous about something, aren't you?"
