Do you think it's okay if I shout at my mother because of her mess?
What will
Because I don't like her lifestyle.
It's mean to yell at your mother. You should settle your differences peacefully.
Oh, I didn't realize my mother was so weak. I thought she could handle being yelled at.
Even if your mother is strong, you shouldn't yell at her because that's not going to get her to change her behavior and it's just mean. If you want her to stop leaving a mess around, you should talk to her able it calmy and politely.
