My flatmates hosted a party last Friday. We all work at the same huge company, and most the guests were also employees there, people I've seen a few times, maybe talked to, but not many I knew well.
On Saturday morning I had plans with my boyfriend for his 25th birthday, so I intended to shower and pass out early.
During the party one of my flatmates introduced me to his coworkers, Faisal and Jason. I talked with them for the better part of an hour before deciding to retire. They were both fun to talk to, interesting. Faisal was texting someone the entire time, so I mostly spoke with Jason, which was totally fine by me at the time because Jason is hot. We exchanged stories about our hometown, work, etc, and he seemed totally normal.
I excused myself to get ready for bed and went to my room, gathered my clothes, and headed to the bathroom. About ten feet of hallway separates my room from the bathroom, so suppose he saw me walking there with my clothes and towel. I took off my clothes and set them on the counter top next to my pajamas, and got in the shower like normal.
