YOUR STUPID..I JUST NEEDED TO LET YOU KNOW THAT
In English, 'your' is the 2nd person (singular and plural) possessive pronoun, whereas 'you're' is the abbreviated form of the the 2nd person (singular and plural) pronoun with the conjugated copula 'be', that being 'are'. Furthermore, generally speaking we leave periods at the end of sentences in English, not all too uncommon in other European languages as well.
