This isn't mine, but my niece's. A while back, my sister and brother in law did that gender-reveal thing where they open a bag of balloons and the balloons were blue, meaning they were having a boy. My niece was devastated because she wanted a sister. But then she had an idea. When nobody was looking, she painted the balloons pink, thinking that would make the baby a girl. For months she continually insisted that the baby was a girl, throwing a tantrum whenever her parents would try to correct her. Even after the baby was born, she would call him Annie instead of Andy.
That was years ago. They're both in their teens now, and she still jokingly refers to him as her sister.
