So what happens when the person who picks the book also happens to be the slowest reader in the group? That's my worry with this setup. Like, our club has this one guy Dave who takes forever with everything, and if he picks something dense like The Overstory and then takes three weeks to finish, does everyone just sit around waiting? Does the group have a backup plan if the picker stalls out, or do you just trust that the person feels enough pressure to keep pace? And what about the opposite problem, where the picker hates the book halfway through and has to lead a talk on something they don't even like anymore?

Been there so many times it is not even funny. My worst one was drilling shelf pin holes on the wrong side of a line I marked myself, then I stood there staring at it like the board moved on its own. The worst part is you cannot just fill a hinge cup hole and pretend it never happened, that thing is staying with you forever. Two millimeters sounds tiny until you watch a door fight the frame every time you close it. Next time you will measure twice and still probably do it once, because that is just how this hobby goes. Guess that makes us even on the dumb mistake scoreboard.
