Book binding. (I can't be the only person who bemoans the way new rulebooks tend to fall apart like a sheaf of dry leaves after about 5 seconds of use).
The only books of mine that are falling apart is an original Unearthed Arcana that I got second-hand and the binding was failing well before it was passed on to me. All of my modern books are in pretty good shape; this is because I generally use pretty hacked-together systems and discourage use of books for anything other than looking up prices for things.
This is a general problem as books have been more and more crappily bound as they've become more mass-market (and because a lot of the old book-binding glues were toxic to work with and now we have some sort of workplace protection for people (this also applies to shoes, my uncles know the exact year cut-off for when Chuck Taylor All-Stars went from "the canvas will go first" to the soles constantly flapping off)).
"Doing a voice". How many people "do voices"? Should they? How do you get better at "doing a voice" if that's your thing?
Kind of. Alcohol, yes. At the table, no. We've lost too many character sheets to a knocked-over beer over the years and as such, you have to place your adult beverages elsewhere. This leads to a lot of kicked-over beer; however, since everybody who hosts at this point has kids, those carpets and floors have seen much, much worse.
What's acceptable to do to a PC whose player is absent from the session? Is whatever happens their fault for not being there, or are there some limits?
Generally we have non-active PCs tag along, watch the donkeys, guard the door in the back, that sort of thing. They're generally played by the DM until it comes to combat, where one of the other PCs will do double-duty (this has been enforced by the DM forgetting about the extra character in multiple combats, which although he doesn't mind, the players apparently do). In these cases, I do my best to keep that character out of harm's way, although not to extreme measures. (There was an instance of somebody's character dying when they were out of the adventure, the player's husband was taking charge during combat and lot their last hitpoint when they were knocked into a campfire and wound up burning to death before anybody could get them out. There may have been some recriminations.) We also play it by ear, as last session we had an absent player who specifically requested that his character do "at least two extremely reckless actions", which was understandable as it fit with the character and we had just started out, so rolling up somebody new was no big loss. (He wound up surviving; no thanks to the actions the rest of the party picked for him though.)
