In the last chapter of The Catcher in The Rye:
A lot of people, especially this one psychoanalyst guy they have here, keeps asking me if I'm going apply myself when I go back to school next September.
What is the real subject? 'A lot of people', or 'this one psychoanalyst guy'?
It seems that the subject is 'this.. guy' because the verb is 'keeps', which does not match 'a lot of people'.
