I HAVE JUST WRITTEN THE BEST SONG I HAVE EVER WRITTEN.

[TinMan666]

You say this girl is your cousin? You disgust me.
I am sure that your uppance will come for spouting such nonsense, and you will look back on your life with discontent knowing full well, that any problem you have with her must be a creation of your own insecurity.

So... you're judging someone you don't know, based on their description of someone else that you don't know, which you feel is unfair even though you don't know either of them?

That seems logical enough to me. Carry on.
