Show Not Tell

I stepped into my room all I saw was with a big fat ugly troll sitting on the bed. I started screaming at her - it was my sister! I felt like a big monster with a volcano in my tummy. I ran down the stairs screaming, I was so upset because I had been cleaning my room for the whole afternoon. Would you like it if your brother or sister came in your room and messed it up? I bet not. Also, guess what! She did not even tidy it up! So I kept annoying Mum but she said she was too busy and Dad was at golf. So I was a troll and did to her room what she did to mine. Guess how I’m feeling?
