I'm going to explain mental health to my 10 y/o brother
Is there a reason that you need to do that?
Cause he needs to know what it is and maybe someday he will need it!
It's good to want someone to know something you think may be important in life. You should always try and do this.
Yeah, I'm going to show him pictures of some mental hospitals, it's a good way to scare someone into never trying drugs.
I think that you should have this talk with him because it is important. I think that you should take a cautious approach though so that you do not frighten him too badly.
