Dear author:
I cannot begin to guess what languages you may have studied in school, but English (any version) does not appear to be among them. Please choose 1 (one) version of English and use it. (Theatre and theater in the same sentence? Really?)
Remember, spell check and grammar check are not your enemies. However, even spell check cannot help if the words are so malformed as to be unintelligible. (What the heck is 'poirson'?)
