The landlord should learn to communicate better with others and communicate well with your mother. Maybe your life will be better, and the methods and help it provides may not be completely out of school or completely incorrect.
You should take the essence from your mother's words and discard the dross, so that your growth can get my help, at least it will not affect your future life and career, and you can have a correct outlook on life and values.
This is the key. Anyway, communicate more with the landlord and less with your mother. Don't let him live in all your things, listen to other opinions properly, and your life will be better in the future! !
