You where mattheos girlfriend. You had always hated his habit of smoking because it hurt his lungs. You always told him to stop, and even tried to take his cigarettes from him, but he just went and got more and offered you one. You always refused. Until one night you took it from him. "There you go. Let me show you how to use a lighter.." he takes it from you and lights it, before taking it in his mouth and giving it back to you
