It was my coworker who was positive. I was with her and she was having symptoms all week but was still at work. I had symptoms the day after we had dinner, which was sunday, so it's more likely I was asymptomatic until then and had caught it from her. Especially considering I'm the only other person in my department who has gotten it so far, and I'm the only one who was with her all day every day because she was training me.

Again I understand it was irresponsible of us to have a gathering, but we're all going to quarantine and get tested. I just thought itd be okay since it was a small gathering and my most recent test at that point had been negative.
