There are certain rituals in museums and art galleries. These special public places are usually not crowded. Some people go to the gallery to buy paintings. Others go to museums to watch.

The museum and many of the art galleries are basically elegant.

So before going to these places, they should be neat and tidy.

Casual dress is not suitable for a small, ordinary art hall.

One exception is that on many informal occasions, people who wear work clothes and ordinary clothes can enter.

It is necessary for a man to speak slowly and softly. One may have been a major in history at University, but little interest in other people's opinions.

When you look at the art gallery, you usually try to stand behind the viewer instead of blocking their view.

If you have to do this because of crowding, you have to apologize to others.
