Question

What he should do to convince his parents to play cricket

Answer 1

it seems like you are an indian cause almost 65% indian parents have this habit of watching their dream come true through the eyes of their children
go and tell your parents that you are interested in cricket . show them all your medals and trophies . and in case you dont have them ask them for a chance .
or maybe a deal will help
promise them that you will do whatever they want but first they shall do whatever you want .
see i can help you if you provide me some more information
