1) 'Dude, my girlfriend and I never talk!'
2) 'It took three years for us to get together, and my girlfriend seems to hate me!'
3) 'Dude, Anthony and his girlfriend never talk to each other!'
'It's a Granthony, man. What do you expect?'
'You make a valid point. Well done.'
4) 'Now that Grace and Anthony are together, the legacy of Granthony can live at last!'
