I have no idea who should allow 12 year olds to make life changing decisions. I have also met 12 year olds with differing mental capacities. Who do you think should allow them to? I definitely dont think the government should decide what a 12 year old does or doesn't do. Im glad that the government doesn't do that. Are you glad? Or do you think the government should decide that the 12 year old cant make decisions that change their own life. What other parts of kids lives do you think the government should have control of?
