Biden can't even remember what he was doing four years ago
I’m not great with time. I can remember details of my life but I don’t generally remember specific dates or even what year something happened. It’s just the way my brain works. There are exceptions, of course, such as when my kids were born, when I got married, 9/11, etc.
One other exception, especially at this point, is anything at all to do with the pandemic. COVID made a mark on our psyches that isn’t likely to go away, so we can recall with vivid detail.
But it seems that Biden can’t.
