"But ultimately, if he is a man, he will make decision on his own, as a man. He won't need his momma to get between him and a recruiter."
Don't think he needs a recruiter to make a decision, either. Like salesmen in all fields, some recuriters are known to lie (sure, son, we'll make a pilot out of you). Unless I know the recuiter personally (and I do know some, including my late daughter's boyfriend), I'd trust my wife more.
He doesn't 'need' one, but a recruiter can provide information useful for making the decision. Might as well make an informed decision, not just a decision based on mommy's pleadings.
