It really can be like night and day. My cat was so incredibly stressed out when we brought her home that she kept “fawning” all over us for the first two weeks. Lots of excessive side rubs and a general clingyness to every interaction. She needed constant touch.
After that she began to settle in and became much more herself: playful, independent, and only sometimes in the mood for a lap or a cuddle.





Yup. Same goes for temp/hunger/thirst. Unless the environment creates a situation that directly challenges that, like arctic conditions, desert, underwater, extended covert ops etc., these things do not serve the story and get in the way.
Plus, a bag of holding neatly side-steps a lot of encumbrance problems and I firmly believe that’s why it’s been a part of D&D lore since at least 2nd ed.
Meanwhile, if the table wants to go deep simulation on all this, the rules are there for that. But I wish everyone good luck with fighting monsters up close in a cave where weapons bigger than daggers are too large to swing, and heavy armor too bulky to be practical.
