Harry Watson - clearly a family member who’s given you his old phone. Not your father - this is a young man’s gadget. Could be a cousin, but you’re a war hero who can’t find a place to live. Unlikely you’ve got an extended family, certainly not one you’re close to, so brother it is. Now, Clara - who’s Clara? Three kisses says romantic attachment. Expensive phone says wife, not girlfriend. Must’ve given it to him recently - this model’s only six months old. Marriage in trouble, then - six months on, and already he’s giving it away? If she’d left him, he would’ve kept it. People do, sentiment. But no, he wanted rid of it - he left her. He gave the phone to you, that says he wants you to stay in touch.
