Is NOBODY wrong in the post ? POST : I'm close to tears now, my older brother and my mother got into an argument causing him to get a backpack and walk out into the freezing cold. It all started because he asked mom where to put the water and I said "on the bottom shelf" this set him off to blow up at me saying "I wasn't fucking asking you was I?" My mom told him to stop and he kept saying that it was him who she hated and was choosing me over him and said said things like "she says stuff like *mocking noises* but when I do I get my ass whooped" and when he went in his room to pack his things I said to mom "You know we can report him to the police because of what he did to Delilah" delilah is is dog who I love but our whole family hates and he has a previous habit of beating her. And now that I realize what I said was wrong and to which my mom replied "This is your fault this happened because you couldn't keep your mouth shut."

AITA?
