My parents are really lame so I usually go for a drive at 11pm (when we lock up our business) to get a coffee and smoke a bowl. One night after grabbing my coffee, because it was raining, I sat in my car and blazed instead of getting out like I normally would.
me: Yo momz I locked up, goodnight.

mom: Ok goodnight son *hug*
*sniff*
mom: Andy you smell like smoke! How come?
me to myself: think quick, fagget
me: The iced cappuccino machine @ Timmy Ho's was smoking and all the smoke was coming out the drive-thru window

mom: ..ok Andy, goodnight

me: *sigh*

I usually walk out the sliding glass door in my room and walk to the other end of the building to smoke but sometimes it's late and I'll just blow smoke out of my room. Most of the time when I do this my dad will wake up ~30min after I smoke and come to my room. Usually I febreeze pretty good but other times I'll start gaming and completely forget.
dad: Andy it smells like marijuana
me: Idno dad
dad: Did you smoke??
me:

What?

Of course not!! I think when people smoke down by the BBQ the smoke comes up and in through my window.
dad: o..ok..
