My son has been playing a computer game for a couple of years now. During the game the players chat with each other. Recently my 18yr old son has been chatting with a 24yr old German girl outside the game. This has escalated quite rapidly into lengthy Skype calls. He is quite serious about her and regards her as his girlfriend. She is coming over to the UK this Sunday and he plans to meet her in London. My concern is that she is older and probably more experienced than my son who has never had a girlfriend before. My other worry is the nature of how they met and is she who she claims to be. My son just sweeps my concerns aside.
