Just got caught by the parents last night

Hey all my fellow ents I know its not Friday and all but I wanted to share my story with you in hopes of relating to each other. So a little bit of back story I am a very cautious toker especially when my parents are home and frients are over. So me and my friends will usually drop by my house before going over to a party or school event and at mouse we'll blaze fat because my parents never come up to my bedroom. I usually have the fan to the window blow out and a towel at the bottom of my door also when we take a break I will spray my smokeout spray so to kill the odor. Last night when me a couple friends got to my house I discovered my parents weren't home and I had remembered they went to the movies and I thought that they had recently left so I wasn't cautious at all. We had just finished half a blunt and were hitting my bubbler that my bro got me for christmas(he is pretty big stoner). I shit brix as I see my parents driving towards the house. So i get the smoke out spray and spray it around the door and stairs( might I add we're on the second floor) and get a towel and start fanning it out but I was too late and it did no good. They open the start and my dad said something that i couldn't make out but then said "oh great!". I'm at the top of the stairs and he walks up halfway and ask "are you fucking smoking pot" all I could manage to say was "yes..." and he goes the other way. My frients all leave also shitting bricks. At this point I actually didn't care and was accepting my fate because I knew it was inevitable and there was going to be hell to pay. My dad comes up later and says what he has to say and the most important thing he said is " if this starts affecting your grades or attitude negatively there will be hell to pay but I had no punishment. Another hour later I was like "Live" and finished my bowl( just kidding that didn't actually happen but I considered it). Yep that's it my ents just wanted to share that and thanks for reading it you did. TL;DR I wasn't being cautious and my parents came home and then my dad talked with me but I didn't get in trouble.
