Renee then told me, "Oh really? Let's see you deal with her then. Jennie, here, talk to [Dissident]..."

Before I could object, Jennie had taken the phone from Renee, and she proceeded to... well, terrorize me! I'm sorry, but no other words are more apt for what this little girl was about to subject me to.

Right away she told me the following, in a very firm manner: "I'm a pretty princess, and I demand that you give me a unicorn this instant! [emphasis her's, not mine!]"

...she's backing her friend up! lol...

Geez! What did I do to deserve that? Especially since I had previously defended her from Renee's admonishment! This is why I'm glad my preference lies with somewhat older girls!

...kind of ironic, since she was just doing work for Renee.

Usually, I tend to avoid these sorts of environments; they tend to come from a limited reference and tend to risk running things over in the course of the things they do do.

However...

At one point, she actually threatened to lock Renee in the bathroom and not let her out until I produced a unicorn for her!

...you did have an awesome chance to lock Renee in the bathroom for doing this to you. :)

I've pulled a few people out of this sort of quid-pro-quo gangsterism. OTOH, it sounds kinda like the three of you had fun, and now you can tell Renee you've got someone who will lock her in the bathroom if you tell her to. :p

Still a bit odd that you're glad you prefer older girls, since she was doing this work for an older girl... but hey, that's the power of, well, something.

Have fun with it next time.
