Uhh...  

Before I got vaccinated, I had a friend and his wife come visit me for a weekend. On Sunday evening, the wife started to not feel well.  Monday morning they left, and by Wednesday they were both sick enough to go to the ER.  Turned out they both *and* their teenage son (who did not come to visit) all had COVID.  (Thankfully, they all had a minor case.)  Tracing things back, we realized that both my friend and his wife had gotten infected the weekend prior to their visit.  So they were infected *and* contagious when they were visiting me.  But I did not catch COVID.  Go figure.

There are a lot of variables to this "highly-contagious, very deadly" disease.  Just because you're in close proximity to an infected person does NOT necessarily mean you're going to get what he's got.  It may have to do with your blood type, or the strength of your particular immune system, or maybe the alignment of the planets.  I don't know.

Oh, and nobody ever said that being vaccinated prevents you from catching the virus.  All they say is that if you *do* catch it, you "probably" won't end up in the hospital or die.  You can still catch it, and if you're asymptomatic you won't even know it.  In either case, you can still infect others.  You don't want to get the jab?  That's fine by me.  It's your choice.
