There is a girl who is very kind to you, but calls you uncle. Why?

If you are really a second uncle's daughter, then she is only honorific (because you didn't make it clear, but it doesn't seem to mean that, does it? );

If you are not relatives, but friends, she calls you this way with several meanings: first, you are old, so I call you this way; Or at least you look old or mature in her eyes; Third, at least you two have a good relationship, otherwise she wouldn't call you that, just like a specific name in a circle of friends, you know.

If you want to go further with her, don't care about the name juwan, but really get to know her. Boiling frogs in warm water, based on your good relationship now, slowly figure it out.
