This is hypothetical. What would you do if you had one son who was a major screw-up in pretty much every way who became addicted to tobacco, alcohol, and methamphetamine, was violent, behaving erratically, paranoid, frequently in trouble with the law, and now got kicked out of his apartment and needed a place to stay? Would you invite him into your home while your other son, a straight-A student and state champion xc runner was still living with you and in high school? What if your criminal son regularly stole things from your A-student son, broke his things, and threatened violence against him and stated at least once (while on meth) he was going to kill him. Would you continue to let this 22 year old live in your home with your 17 year old son? What would you do?
