Have you heard from Singles' Day (Nov 11) in China? Many people stay up lately that night, shop online to get big savings. Well, the US has something like it calling Black Friday.
Black Friday is one of the bigger shopping days in the US. It always falls on the day after the Thanksgiving holiday. On this day, store will offer special deals, just like on Singles' Day in China. On Black Friday, shoppers will often wake up very early to wait in line at stores after they open. They might start wait in line as early as 2 or 3 am. Sometimes, the crowds will be such big that it is impossible to get inside the store. People sometimes fight over things because there are only a few are left.
