Does it mean the same thing as "keep me awake" No.
or "keep me focused on something"? It's hard to interpret without a context. Where did you encounter this phrase? It might mean 'Keep me from being confused."
I heard it from somewhere, but I don't really remember the context. "keep me from being confused." so.. you guess "keep me straight" means like "let me get this straight"?
thanks for the reply. Seems like this forum is full of helpful people.
