They didn't remember the 6th anniversary of the day the round red scamster went to his richly-earned reward, and at the DUmp, the freepers killing Andy was as big an event as 9/11.
Hell, the 4th anniversary was the last one the primitives remembered, in 2009.
They needed prompted by us for the 5th anniversary in July 2010, and then of course prompted again for the 6th anniversary last July.
This, for a guy hundreds of primitives pledged to remember "for the rest of" their lives, he being branded forever on their hearts, minds, and souls, the night of July 9, 2005.
I'm sure we'll have to prompt them again next July, for the 7th anniversary.
One gets the impression the primitives were very troublesome to toilet-train, as they don't remember anything.
