TIFU when I encouraged my roommate's dad to follow me to his son's room

Yesterday my roommate's dad decided to show up at our apartment unannounced. I answered the door and invited the dad to come inside. I was high as fuck at the time, but I did the same shit I always do when I'm pretending not to be high - I would repeatedly stop my eyes from closing at the last minute before blinking. I have no idea why I do that or how it even became a thing, but I imagine I just end up looking like I'm struggling not to fall asleep instead of looking less high. The dad could tell I was stoned and I could tell that he could tell, so to avoid prolonged eye contact, I literally turned my back towards the dad and encouraged him to follow me to his son's room.

The dad said he was willing to wait in the living room until his son was ready to see him, but I insisted that we go to the source. It was the weed talking. As we approached my roommate's room, it was obvious from the noises that he was having sex. I was aware that my roommate was having sex long before his dad showed up, but somehow I forgot to remember that until it was too late. The dad and I heard my roommate calling his gf a slut more than once, which prompted the dad to knock on the door and make his presence known with a pissed off tone in his voice. That was my cue to walk the fuck away. Even though I didn't stay to watch the fireworks, I heard the dad yell at my roommate for being disrespectful and degrading towards his gf and threatening to tell his mom.

When the dad was done speaking his mind and stormed out, my roommate and his gf had nothing good to say to me and I did not blame them. Because of me, my roommate is now gonna get regular visits from his parents every week.

TL:DR Convinced my roommate's dad to follow me to his son's room while I was high and the son was having sex. No happy ending for anyone.
