Re: many more fish
Keannu, a lot of what teachers and books (both good and bad) tell us is general advice. There are almost no absolutes in language. I think that some of your frustration with English stems from the fact that you seem to want a watertight answer for everything; one seldom exists. Although I occasionally break my own rule, I strive not to use the words 'never' and 'always' when talking about English.

I would suggest that you try to take a slightly more relaxed approach to the language. General rules are (generally) helpful. It's not the end of the world if not everything can be neatly slotted into a precise position in some artificial grid.
