Why do Americans never take off their shoes when they sleep?

Americans don't have the habit of taking off their shoes as soon as they come in. In their eyes, this is a relatively casual thing (as in many countries in Europe and America). This is done on movies or TV to show rejuvenation.

They sleep without shoes, but sometimes they find it too troublesome to take off their shoes. If you go to American homes, you will find that you can wear shoes in almost every room (to be honest, only a few countries in the world take off their shoes when they enter the door, such as China and Japan, as well as Indian and Korean ... cultural differences).

Just as we in China usually don't care about eating and drinking soup (which is very bad for foreigners), Americans don't care about taking off their shoes, but they still take off their shoes at home (such as getting up in the morning and taking a bath at night).

In American families, you will find people who wear shoes and people who don't wear shoes standing in the same room, which is normal.
