I'm going to get on my mom's case for working till it kills her
Do you think it's something that you truly need to keep on her about?
Yes, as I'm truly concerned about her wellbeing.
It is good that you are aware of how your mom is feeling. Sometimes moms do not take care of themselves.
Right, I'm just looking out for my mom. I worry about her health due to her overworking herself.
Your mom is fortunate to have you and that you can about her health and how hard she works. It's important to support family members and at times that means pointing out things that concern you.
