I'm going to tell my mom about my brother's drug use and school skipping
What is telling your mom going to change about the situation?
I just want her to know how irresponsible he is.
It is the right thing to do to tell your parents about your sibling using drugs and skipping school, even if you reason is wrong. This is something that parents need to know about so they can do their best to help their child.
My parents would do more harm than good but I guess I do have to tell them.
I hope your parents do not do more harm but you are doing the right thing to talk to someone about your concerns for your brother.
