A person who's been traveling a lot comes back home. <br/><br/>Can you still say: Wow! How long have you been gone? Or does it have to be:<br/><br/>Wow! How long were you gone for? And can he reply with:<br/><br/>I was gone for a whole year. Or <br/><br/>I've been gone for a whole year. <br/><br/>Please proofread. Thank you!
