Do you know the word “brunch”? On weekends, many people like to have brunch—late breakfast or early lunch. People usually have brunch between 10:00 a.m. and 2:00 p.m. on Sunday because they like to get up late after a week’s hard work and they want to enjoy brunch with their parents, children or friends. That is a relaxing and interesting way of eating for most families.
