This 6" by 4" postcard says "I pissed away my immortality counting things. That was my passion? Goddamn numbers?! How many years did I waste? 500? 501? 502? Ah ah ahhhhh fuck me" on the front.
The back says, "How are you wasting your gifts?" If that isn't sobering, I don't know what is.
These postcards are sold in pack of ten.
