Idk this is ambiguous stuff is how you can waste an hour with your players ripping everything off the walls because they think you being unclear is a signifier of something. Like you have to be more clear than ambiguous over all because they are playing a game and unless they are checked out will drill down into it. Maybe you don't mind them wasting an hour investigating a pointless room or doing everything they can on an object because you were vague about it but it's not rewarding for players. Like being vague about a rock is going to have any player take it with them compared to saying "it's just a rock." Maybe you can take those moments and make memories from improv'ing with them but itll get exhausting for both sides after awhile.
