Black Friday

    Thanksgiving Day is always on a Thursday. The day after it has been known as Black Friday. It is the start of the holiday shopping season, and it has been the busiest shopping day of the year in the US since 2005.

    Most stores offer big sales on Black Friday. They open their doors quite early in the morning. They try to attract shoppers with big discounts（打折）. Some items（商品）like TVs and cloths are much cheaper than usual. Stores may even lose money on these items. They hope that shoppers will buy gifts for other people while they are in the store.

    Black Friday is a great time to go shopping. However, there are problems. The biggest one is that there are not enough low-priced items. Each store may only have a few. These items are in great need, so people stand in long lines to get them. They may wait for three to four hours before a store opens. They may be hoping to get a low price on a TV or computer, but not everybody can get one. Some people leave, disappointed.

The situation makes people worried. Some Black Friday events have been crazy. There have been fights over toys among shoppers. Some workers have even been hurt by large crowds. But most Black Friday events are safe and fun. Still, if you plan to go, you will expect large crowds and a bit of pushing.

Now people all over the country take part in Black Friday events. It is even spreading to other parts of the world. Stores have held Black Friday events in the UK, Australia, and Brazil since 2012. In Mexico, stores offer a weekend of discounts every year. They call it ‘El Buen Fin’, which means ‘the good weekend’ in Spanish. I guess people everywhere like to buy things on sale.
