Hello! I'm am wondering what the correct sentence would be when I want to say: <br/><br/>Children commonly wear carnation(s) on the/their chest(?) <br/><br/>Cats like to chase their tails.(?) <br/><br/>I'd appreciate if you can give an explanation why. Thank you in advance. <img class='emoticon' style='Width:19px;Height:19px;' data-delaysrc='https://uat-englishforward-forums-backend.s3.us-west-2.amazonaws.com/Emoticons/7.gif' src='https://uat-englishforward-forums-backend.s3.us-west-2.amazonaws.com/Emoticons/7.gif' alt='Emotion: tongue tied'/>
