Mine is constantly with his girlfriend - either at our house or hers (stays round a lot at hers in separate rooms - her parents are far more liberal than we are).
They both seem to have stopped seeing other friends and only want to be with each other - have been going out now for just under a year.
Can barely say a full sentence to us but gets on great with her parents. They think he's wonderful. Looks at us like we are shit and has no time at all for his younger sister.
Does his homework and class work okay but although predicted As for his GCSEs is working at Cs due to his lack of motivation.
Tried all sorts to better the situation - punishment and bribery but he remains steadfast in doing what he wants. It's likes he's mentally already moved out of home and just waiting for his actual age to catch up.
