There is a saying that when your son becomes a priest, you have already paid your dues and paradise will be waiting for you. In the olden days, parents would spend a fortune just to have a priest in the family. But it's not a very attractive prospect now since most parents want to see their grandchildren particularly if they have only 1 child and that is the son who can become a priest. Besides, a priest cannot take care of his elderly parents. That is the reason why most parents do not encourage their sons to become a priest.
