Sometimes people feel left out or alone. This can happen at school, at home, or even when you’re with others. It’s a feeling we all get once in a while. When someone feels like they don’t belong or are not noticed, we say they feel isolated. To talk about this feeling, people often use idioms. These are phrases that don’t mean exactly what they say but help explain how someone feels in a more interesting way.
For example, someone might say “I’m in my own bubble” or “He’s on an island.” These sayings show what it’s like to feel alone or separate from others. Learning idioms about isolation helps us understand others better. It also helps us express our own feelings in a smart and simple way.
