Is AUTHOR wrong in the post ? POST : So we were making a project and this girl wanted to make a handle and my friend wanted to help so I let them be,When they were making the handle I noticed the girl playing with the cutter and then a few minutes later I see my friend's finger bleed so I asked what happened and he said that the girl accidentally cut her and the girl was telling me that she didn't while 2 of my friends swore that they saw her did it. 

Then I said okay forget this happened lets just move on then we forgot about it for a little bit and the girl messaged me 2 weeks after it happened and told me that I was judgemental and rude for assuming she cut my friend and I told her that my friend told me you did and she said that my friend told his mom that he cut himself by accident and I was confused so I asked my friend why he told his mom that and I found out that his mom was super strict so if she finds out that someone cut her she would rush to the girl. 

At this part my friend was just protecting the girl and the girl is still blaming my friend for cutting himself then me and the girl got on a arguement which made her mom think im the bad guy for protecting my friend and lying about what happened so I told her mom that it was the truth and she told me to not start it again and I told her that she started it and she said I was lying again so AITA?
