It's all in your 'presentation' IMO. When I lived at home, I used to smoke in my room. Before I came out, I washed my hands, brushed my teeth and rinsed, and then Visened up. Gave it 5 minutes and then I would come up. The most attention I got was "Why do you look so sleepy" to which I would just reply "Because I am" and that was the end of the conversation.
