Hi! My name is Gabriei I'm 16 years old and I'm in Year 11. I've got a brother and a sister, and we live with my mum and my stepdad. We've got a pet dog. Bouncer, I'm new to the school, but I'm not new to Birmingham.
I love living in Birmingham because it's got two really good football teams and I'm a football fan. My stepdad is a Birmingham City fan, but my brother and I support Aston Vila. On Saturdays, we always watch football on TV together. It's realty noisy!
