Many cultures have different ideas about how much personal space is needed to feel comfortable.

Personal space is like a no-fly zone or a bubble around each person. It is an extension of them. If another person, especially a stranger, enters that space; it might seem like a personal violation.

For many Westerners, if they can feel someone else's body heat, the other person is definitely too close for comfort. However, people in South Korea have a different concept of personal space. It is not uncommon for strangers to stand or walk closely with each other on the streets, shopping centers, or subways. Also, Koreans tend to crowd together in close proximity, especially if waiting in line, even if there is more space around them.
