An imaginary friend is like a pretend friend that someone creates in their mind. It's like having a friend that no one else can see, hear, or feel. It's kind of like when you play with dolls or action figures and imagine them doing things and talking to you.
Sometimes, kids create imaginary friends as a way to cope with things that are happening in their life or to have someone to play with when no one else is around. It can also be a fun way to use your imagination and creativity.
It's important to remember that imaginary friends are not real, but they can still be special to the person who created them. If someone you know has an imaginary friend, it's important to be kind and understanding towards them and their friend.
