I think my friend may be otherkin. She doesn’t know what it is, or even that it exists- but I think she would like to know about it. However, I don’t want to by just showing her otherkin and asking her if she thinks that’s what she is. What should I do?

Ask her if she’s heard of otherkin, and what her opinion on them is, if she has. If she hasn’t heard of them, introduce her…
