Have you had Covid before? Do you have the antibodies? Sometimes you just don't know. I felt sick at one point. It wasn't bad enough to go to the doctors. Did I have Covid? Maybe.
I mean come on it's bad enough to get the flu once a year? Am I right? Have you gotten it yet? I think I did around New Year's. I say "I think" because that is what my daughter got diagnosed with when she returned home after Christmas.
