Gender variance means that sometimes people don't feel like they fit into the typical categories of being a boy or a girl. Just like how everyone likes different things and has different personalities, some people feel more like they are both a boy and a girl, or neither a boy nor a girl, or something else completely different. This is okay, and people should be respected and accepted no matter how they feel about their gender. It's important to listen to and learn from people who experience gender variance to understand and support them.
