She is one of Satan's demons

I should have known my sister's daughter would say or do something to spoil the good time I had today with my little niece. We went to the places she wanted to go and did the things she wanted to do today. And we went shopping. It was fun! Then we went home. Satan had a willing demon ready and waiting to spoil our good day.
When we walked in the door, she didn't talk to me, only to the baby. She already had a chip on her shoulder. Talking loud for no reason and acting ignorant. I asked why are you talking so loud. She started screaming louder and yelled because I'm grown and I can talk as loud as I want to. I said grown has nothing to do with it. And I walked away. My sister tried to make jokes to ease the tension. I decided to get back in my car and leave.
I pray for the Almighty's vengence upon this demon. I am so sick and tired of her arrogance and loud ignorance. She doesn't care about anything nor anybody. I can't sleep peacefully in this house anymore. I don't trust her. Who knows what she might do while I am sleeping. Maybe I need to at least file a police report in case something happens to me.
