We have a way of indicating the speaker hasn’t understood something. It is a way of saying “Please explain what you mean.” Guess what it is. Let’s listen to the following mini situational dialogue to get the answer.
(Scene:It happens between a master and his servant.)
Master:You should put these boxes over there. Are you following me?
Servant:Yes. I understood all of your instructions.
Have you got the answer? It is “Are you following me?” If someone asks you like this, you might as well say, “I don’t follow you.” “To follow” here means “to understand the explanation or meaning of sth ”. For example: I couldn't follow his argument at all. Here is an another mini situational dialogue:
(Scene:It happens between a son and his mother.)
Son:I am not sure what you mean when you say I don’t work hard.
Mother:I mean that I think you are pretty lazy.
Son:Idon’t follow you. Maybe there is something wrong with my ears.
