Which sentence uses the word you’re correctly?
i always see you’re mother at the bookstore.
is it you’re mother who wrote that book about chimpanzees?
it looks like you’re a pretty good writer yourself.

The answer is: It looks like you're a pretty good writer yourself. Hope this helped.

The answer is: It looks like you're a pretty good writer yourself. Because the word you're is a compound word made from the words you and are, so if you're not sure about it being used correctly, always look to see if you can replace it with you are, if the sentence sounds funny then it is not being used correctly. Hope this helps.
