The old man And the sea

[wenenson]

Today I have two questions:
First ,"I know you did not leave me because you doubted."
What does this sentences mean?
In my opinion,"you did not leave me.!",but it is wrong.
The other,"Come on and eat.You can't fish and not eat."
In my opinion,"YOU can't fish and You don't fish."
but it is wrong too.
And please give some examples.
Think you.(They are both in <<the old man and the sea>>.)

The first sentence means that the speaker knows that the listener did not leave because he had doubts, probably about the speaker. In other words, the listener left for another reason.

The second sentence means that the listener will not be able to fish if he doesn't take in nutrition to keep up his strength. "You can't fish" either means "is not physically able to fish" or "doesn't have permission to fish". In this case, it means the first. "You don't fish" means that "doesn't know how to fish" or "never goes fishing".
