John paused just as he was about to take a drink. He knew she was right. A small smile appeared and vanished as he took a drink, downing most of it in one go before putting the glass down. Next he took a cigarette from the pack on the table and lit it.
"Yeah you're right. You should head on home" he said, before taking a drag. He closed the lighter and placed it back on the table before plucking the cigarette from his lips. "Get some rest when you're done eating, yeah? If you're not feeling knackered now it will eventually kick in and when it does, you should probably try and find somewhere comfortable to sleep" he pointed out. Not that he really needed to.
