A phone rings.
The man answers it, "Oh, hi Dad" he says, "You're in Dublin and you're calling over? Okay then, see you in a short while".
The man hangs up the phone.
There are the sounds of frantic activity from within the room.
"Hey" he calls to his flatmate, "my dad is calling over in a few minutes, can you see any signs of my having been smoking in here? Oh SHIT cigarette packets! FUCK! does this room smell of smoke?"
All pretences at being cool are abandoned.
