There is no smoke without fire

Our flat mate is finally in love. On Tuesday he invited us all to meet his girlfriend. At the beginning of the dinner, my boyfriend passed our flat mate a cigarette. He refused it and his girlfriend explained he didn't smoke.

Which was a surprise, as I know he smokes quite a lot. Since I do not allow my boyfriend to smoke in our room, he always goes to that guy's room and they smoke together. I pointed this out of course.

My flat mate seemed quite embarrassed and he explained to his girlfriend that he only smoked a few.
