I am not sure if this is something that runs in families or is just a quirky anomaly of my family, but imaginary friends are a thing for us. My sister, Annie, had one for quite some time. Two of my three boys had multiple imaginary friends. So as a group, my family just went with it and welcomed them into the family.
For any child, living inside imaginary lands offers an escape, a place to pass the time. For a transgender girl struggling with questions of identity, the ability to imagine a place where people see her for who she is, treat her as a girl, and loves her as a daughter becomes essential for her survival.
