i say the father needs to realize that he is hurting his son more by doing that than helping him.
He is showing that his son can go to him whenever he needs something. IF the father keeps letting his kid get stuff even though the son is the one to blame then even when the kid is married and has money problems then kid will go right back to mommy and daddy even though he is now grown and supposed to be able to take care of his family.
Children need to realize that things get tuff and sometimes your the only one can fix it. You cant go back to mommy and daddy for everything.
