It's ours. This is my boyfriend's and my car. It's yours. This is your pen. It's theirs. This is my parents' house. It's hers. This is my sister's bag. It's his. This is John's dog. It's mine. This is my book. https://339efcb25eb75e967b0d-ff8eeadd950d51fd1fc939dca75b3973.ssl.cf1.rackcdn.com/assets_green.swf
