Input: Text: obligatory, this didn't happen today. let me take your minds back to the summer of 2016.

it was towards the end of june that myself and a group of my friends decided we would go to the party location magaluf, in spain. the first night we went out at around 11pm, little did we know this was an early start to the nights out there. we stayed out until around 6am and headed back to the hotel room.

we then went out the next night, and the next, and the next, and then one night, i commited a fu. 

all i remember was knocking on my hotel room door. opening my eyes, looking down, staring face to face with my flaccid phallus and unable to work out whether i was in a dream or not. i pinched myself, and it hurt.. so i used that as evidence to support the case of reality. i stood there for a few moments, banging on my hotel room door, figuring out what the fuck to do. i was completely naked, locked outside my hotel room on the 3rd floor of the hotel.

i had a few options; wait for someone to open my door if i could wake them up, take the elevator down to the bottom floor or run down the stairs to the bottom floor where reception is. i didn't like the last options, so the banging continued. a few moments later, a security guard came up to the floor with a spanish flag and the biggest fucking smile on his face. i wrapped the flag around myself and we proceeded to go downstairs for me to get a spare key.

as i was walking with him, i heard people laughing and smirking and making jokes and such. to be honest, magaluf was probably the best place it could have happened as it was around 9am (everyone would be asleep) and it's a party place, so things like this must happen all the time. i got a spare key, went back to my room and slept it out. the only reason i knew it wasn't a dream was the fact i woke up with a flag around me.

i have an idea on what happened. at home in my bedroom, i have to stand up and walk out of my room, turn right and then there is the bathroom. the hotel room was laid out almost exactly the same as my room, except the bathroom was on the inside of the door... not the out. i think i must have woken up (i sleep naked btw, it's so much more comfy!!!), my brain still asleep and in autopilot must have gone and walked out of the door to find the bathroom, realizing it's mahoosive mistake and then proceeding to slowly awake to the sunshine and laughs as it was making my hand knock on the door.

i want to go back :(
