Hey kiddo, have you ever gone shopping on a Sunday with your family? Well, Sunday shopping is when stores and shops are open on Sundays so people can buy things they need or want on that day. Some people think that stores should be closed on Sundays, just like how schools are closed on weekends, because it's a day for rest and family time. But other people think it's okay for stores to be open on Sundays because it gives them more options to buy things and it helps the stores make more money.
In some places, there are laws that say stores can't be open on Sundays, but in other places, it's up to the store owners to choose whether or not to open on Sundays. It's important to remember that even if stores are open on Sundays, people should still take time to spend with their families and have a break from work and shopping.
