Someone at work tested positive but He is not from my department. We saw each other after work as we was leaving the building, he asks how we was doing and how the family was and I said all is well, showed him a pic of my son going back to school and how grown up he is now. Only took about 10 seconds if that, I was wearing a mask but his was slipped down a bit so it wasn't on. Haven't been contacted, only those in his department have. Isnt it 15min close contact without masks?
