My friend was acting defensive when I told this, why?

[Believer]

I was scrolling through my facebook homepage, and I saw that my friend had commented on a picture of one of her friend's. It was a picture of a letter from a poetry contest that I had entered. It was a scam, fake, or something, but they wanted a lot of money for the book and other things. I told my friend, to tell her friend, to warn her before she paid the money(I didn't pay the money). She got defensive, saying that it was her friend's choice, and the she wasn't getting in it. She said she was proud of her, and I told her that I wasn't jealous of her. I mean, I entered in the same contest and got a letter, I wouldn't be jealous.

[hhhhhhhhhhhhhhhhhh]

She feels like it's a competition between you two.

Reassure her that this isn't the case.
