"One of the signs says "grandma's house", and the tag says "for grandma". Can you help me out, Farlys? I'm not good with puzzles"

I still remember the first time I had players spend an hour trying to decide how to approach a door. And it was just a half-rotted door almost ready to fall off it's hinges.

I remember the time almost an entire play session was spent arguing about how to get to an island in the bay. We were in a city, and to be fair the PCs were fugitives hiding from the regent of that city, but getting to the island itself was always meant to be just as easy as hiring a boat.
