history: I am Junior Manager and one night I have to stay at office for whole night as I was having excessive work that day. So, everyone in the office left and I was all alone in the office. There was pin drop silence there and even I can hear the ticking of the clock. Even a single noise scared me that time.
current: I stayed alone at night in a office due to excessive work and was much scared.
next: Just you. No security?
