So, the My world this time will be about my sister, i don't even know why I chose to do it of her, because she's so annoying... Well I'm going to explain all of her, now, so if you are interested in her, keep reading.
My sister is called Alexia, she's seven or eight years old, i don't know because i don't pay a lot of attention at  her, but I do know thather birthday is on the 27th of April. She goes tu Ruiz Amado school, and studies very well, even though she is really lazy, she arrives home and does nothing, all the kids are doing homework and she doesn't even open the backpack.
She is the most annoying person on earth, seriously, I'm doing my homework or studying and she comes to my room and bothers me and starts messing with me, and I get mad, because I was suposed to be focused on my homework and she desconcentrates me. She also has good things like, she is always happy, has lots of friends and takes care of them, she helps them, is really ressponsible at school...
