go rainbow dash go!

HI EVERYPONY! I just want to say it´s an account that my sister and I are sharing (because we only have one computer in my house)
Ricardo: I´m 18 years old, I live in Argentina and I love to play basketball, I love it so much that I play it everyweekend. I play it even if it´s rainning (yep, I´m a crazy guy.) I was a member of the local basketball team but I have to left it to go to the university. I love to play video games and read books with my sister... well, I and my sister spend most of the time together so we practically do everything together.
Rosana: I´m 17 years-old, I love to paint and read books.
I´m a member of the local volleyball team of my town and one of the best students in my class.
I´m a very shy person so don´t spect to talk to much time with me.
I spend most of my time with my brother (because when I´m with him I feel more... free to express my feelings and ideas.)
I hope that you could understand my text and please tell me if I made any gramatic mystakes because I´m studying english and any kind of help will be wonderfull to me... if you´re free... and if you want to help me...
