lol! My youngest son was 8 when he was leading teams of adults (young as 20 old as 70) in raids.
I disapprove of your advice.
My sister does, too. I game with her son as well. Some of our children are now fully grown, with my oldest 2 having families of their own, a few still in college, with only one left at home still in high school. So apparently my track record is adequate for my requirements.
It takes a LOT to presume you know everything about a child, their home, their parents, etc...
I am not as capable to pass judgment on others as quickly as you can without knowing anything about them. Good for you.
