Here are a few of the many instances of bad grammar in this story.
(1) The phrase "...they both threw a basketball..." implies two throwers but only one ball. I think you mean to say "...they each threw a basketball...", eh?
(2) Why do you put an apostrophe in the word "does"? Is it because you have seen words with an apostrophe before a final "s"? The apostrophe is properly used both in contractions, as in "don't" (meaning "do not"), and in possessives, as in "Jane's" (meaning "belonging to Jane"). I think that it is this latter usage that has you confused. All words that end in "s" do not require an apostrophe before the "s".
(3) I believe you also used the word "advise", a verb, when you meant to use "advice", a noun.
(4) Further, you exasperatingly place a semicolon (";") before the verb in many sentences. A semicolon is very much like a period -- the entire phrase preceding it should be of the form "subject - verb - object". One simply does not put a semicolon in the middle of a simple sentence.
I believe your stories will be better received if you take the time to master the basics of grammar and usage.
