(TL;DR at the bottom in case this is too long)
These are old dorms on the campus I was at, I don’t live in these anymore this was about a year ago. Basically they had these circular buildings with 4 floors. There was no hallways, it was all balconies that lead to everyone’s dorms. (I’m gonna try to explain the layout as best as I can) There’s 4 of these hexagon shaped towers with a dorm room on each side of the hexagon and on all 3 floors (not including the ground floor since it’s on the ground) there’s bridges that lead to the other towers that make a square shape with a tower on each corner. My dorm is on the bottom floor.
It was a holiday weekend so most (certainly not all) students were gone including my roommate. It was like 2am, I leave my dorm room unlocked and fully dressed, I go to a top floor of the tower that’s on the opposite corner from me, and I hide my key in a little hole for water drainage (not a pipe just like a hole so it falls out the side). I walk back to my dorm, strip off everything, no socks or shoes or jewelry, absolutely nothing on to be as naked as possible. I open my door, after the coast is clear, I lock my door, and then I shut it.
