It does not get worse than a dear son that pleases himself.
Note: There is nothing so exasperating to parents then to have their wishes ignored by a beloved child. Parents want the best for their children. They want their children to benefit from their experience in the harsh realities of life. They want them to go to the right schools. They want them to enter the right profession. Then they want to kill them when they demonstrate a mind of their own.
There is little play on words in the Irish of this proverb. Literally, this proverbs means, “His own council for a dear son and it never got worse.” “A chomhairle féin a dhéanamh” is an idiomatic way of saying “he does what he pleases.” He only takes his own advice. Of course, from a parent’s perspective, this is the worst advise he could get. He who takes his own council has a fool for a councilor.
