Stopping Smoking

Larry decided he could cut down on smoking by smoking mine. He said he is smoking less. I said he is smoking more of my cigarettes than I do. He said but he is smoking less than he did. I am pretty sure it is annoying putting up with somebody going through withdrawal, but it is pretty annoying having to go to the store because I'm going to be out of cigarettes and I can't tell when because I'm not the only one smoking them. The reasonable thing would be for both of us to quit.
