TFW you go to local coin shop and don't buy any coins, but pick up these 2 books because they're on sale and you've seen just enough 1980's pics/memes and heard the Satan Klaus "cyber pandemic will make COVID look like a small disturbance in comparison" soundbite enough to think paper books might be the wave of high-tech.
