sports

 

sports is one of the best activities which help us for health, i play bloleyball since fifth grade, i like its gameplay, it is different from the others, and fun for me. i´m good at volleyball, i can move well, and my friends play too. the school held a classroom tournament, wich i entered, it was very entertaining and difficult, in the end we lost, but i loved that competition.
