I always thought I had a hard time putting together faces and names even though I have a pretty great memory otherwise. So one evening at a party with mostly strangers I made an effort to really ask everyone their names make mnemonic devices and repeating them like I would for stuff I actually care about. At the end of the evening I still knew the names of ever single of the 30 something people I just met. Which proved to me conclusively that I just don’t happen to give a shit.
