Geez what next, even those is their 30's, 40's? You cannot protect your children forever and at some point people have to make their own mistakes in order to learn. You raise your kids to the best of your ability, but at some point you just have let go. Adults, wether they are mature or not, make adult decision and have to deal this those consequences. Trying to prvent this will only lead to further disaster.
Not true. Government needs to control this! :P
