We live in mini apartments here at the center. Mine is the last one at the end of a very long corridor. Each apartment is identical from the outside, and I have found myself stopping at the wrong apartment a few times already.
Tonight, I was coming back from the gym and absentmindedly winding my headphones up when I got to my apartment. I was surprised to find the door unlocked and even more surprised to find someone in my bed. I turned around to see if my roommates were playing a joke on me and saw a stranger at the table.
That was when I realized I made a mistake.
I walked into someone else's apartment. I just froze and said "this isn't my apartment," then turned and walked out the door with a hasty "welp, bye!" What an impression. I'm definitely off to a good start here.
