He is becoming an adult and beginning to make his own choices.
Support him in whatever he may choose to do.
He was gifted the magic of one life ... HIS life:
He is incapable of living anyone elses life, no one else may choose for him.
You have supplied him the wisdom and courage to make it this far,
and for that you will always be his hero.
Every parent is afraid. But he wouldn't want you to be.
