I know the main idea behing the reported speech (shifting of tenses) but one of the textbooks I have says:
I like pizza.
He said he liked pizza.
But I think that if he likes pizza, he likes in in general and he still like it when we report that statement of his/hers. So I think it should be:
He said he likes pizza
in case he is still alive and has not changed his mind. Is that correct?
