Modern rule sets stress rules for most things you encounter or do. Old School however is about rulings not rules. In such a situation a good old school player needs to trust his GM. If the GM doing a bad job,of you have every right to deal with it like an adult , leave the game or whatever you need to do and of course a bit of grumbling is a grognards privilege but push to shove, the GM's word is law. Deal.
#3 Explore the world.
Its not a static world or a railroad (a few adventures accepted) and its not a video game. Feel free to explore, poke and prod and treat the world like its a living place, suggest things that might be there and more.
