I've always wondered if they can smell when I'm smoking in the bathroom. I blow it directly into the vent that leads outside and spray Febreeze after I'm done. The reason I'm asking is because sometimes is smells fucking awful in my bedroom, which is located right under their bathroom so I'm pretty sure I'm smelling that guy when he takes a shit. Anyone have any experience with this? Can't smoke outside because both front and backdoor lead right out to the streets, no yards or privacy of any sort.
