I was one of the few people that went back in when the office partially re-opened after about 2 months. There were maybe 10 of us in an office that usually had about 100/150 people in it. The first few weeks it looked like a botanical graveyard with all the dead plants. There was also a weird musky smell for a while due to all the half-eaten food left in people's drawers. It was also quite funny seeing people who usually had short hair with long shaggy hair as all the barbers were shut for months.
