I suspect it must be because their noggins are just so a-pounding with those all-consuming little rages that they can no longer see correctly. Either that or they are so fixated on those they love to hate that their feeble cerebrals can no longer keep all the names straight.
But far be it from us here at the Tattler Cognitive Research Institute (TCRI) to point out an apparently congenital problem without coming up with a solution. Maybe the LVN should establish some sort of flash card system? Or break out the wood blocks? Powerpoint presentations? Voodoo dolls with "Hello, My Name Is" adhesive lapel tags? Or, taking Mayor Mosca's lead, perhaps they can get other cities to help them out with their problems?
But whatever the reason might be, this one truly takes the cake.
Not that they usually aren't, but consider today to be an open thread.
