Bestie slapped me.

I was at her house to take care of some business as usual and she was just getting ready for bed. I can't remember what I said to her, something like, "It's time for bed," and she got angry and slapped me. Oh yeah, she accused me of pulling her hair. I was helping to dry her hair, I sometimes dry her hair while her mother takes care of other things for me and she was saying we should play xbox or something. It doesn't matter, but what matters is when she slapped me and it wasn't zero force, I laughed.

She slapped me again, harder, and I said, "that's enough, go."

She said, "you need to follow directions!"

I said, "no, I'm the adult." And tried to headbutt me.

She then ran and told her mother that I pulled her hair. Her mother said, "what were you doing that he pulled your hair?" she feigned innocence and yes her hair got pulled but it was because I was drying it and she tried to headbutt me but only succeeded in getting her hair pulled, it seriously wasn't my intent.

Her mother saw right through it and said to her, "will you promise never to do that again?" she didn't speak as she faked her sulking. Then she turned to me and said, "will you promise never to do that again?" and I immediately said, "Promise to never dry her hair again? Because that's what I was doing, so no."

I never had a little sister, but this is exactly the kind of things little sisters do.

Look, her bedtime is around the same time as mine and I was tired, I'm a workaholic, not a playmate for hire, not her toy, not her servant, I'm her friend yes, but you can't force friends to do what you want, believe me on that one, it's not what friends do.
