If someone sees you one way and changes their mind so that they are seeing you differently then that is the meaning of the quotation. It is a mutual event. If he sees you differently then most likely you will see him differently.
Most likely you have had arguments with your parents or siblings. That will mean that there is a momentary disconnect between you and your parents or siblings. It's usually not permanent. It is just something that has happened and if you relax and take it easy, most likely by morning it will be forgotten.
