Personal space can be defined as the comfortable distance between you and another person that you are talking to or stood next to. Some people like to measure their personal space by the lengths of their arms. You might have done this in PE lessons, where you stick your arms out and move them around you to make sure you’re not stood too close to anyone. Think of it like a bubble around you that protects you. You can allow someone into your personal space if you want to, and you’re comfortable with it. These people should be people you know and trust, not strangers. If someone invades your personal space, it means they are too close to you, and they are making you feel uncomfortable. For example, if you are in a queue at the shop and someone comes and stands right behind you, nearly touching you, this will feel very uncomfortable - they are invading your personal space. Children will learn how to set boundaries, and respect other people’s boundaries when it comes to personal space. They also need to understand that a stranger should never touch them or invade their personal space.
