I had this obnoxious remark said to me in my mid twenties, shocking, hostile, unpleasant, unnecessary.
Your son is hardly a beggar though is he? What you chose to do as a student
should not be his burden.
Cleaning camper vans / toilets is not an occupation many people would want
for their sons nor expect them to believe this was all they were worth.
Mine worked in a plant nurseries through most of the summer, cycled there
with a stack of sandwiches and drinks, out from dawn to dusk, low pay,
but learned to deal with the public constant questions, became knowledgeable about herbs, plants, worked in the rain and sun, learned patience and fortitude.
He was slim in June, by September he had muscles, a broader physique,
larger size boots, suntan.
Better than cleaning toilets. He had his own bathroom at home btw which he
kept clean along with his bedroom, no stranger to the bog brush.
I cannot imagine it happening, but if he had come home said, “I am going to clean toilets in a pub” then I would have thought I hadn’t brought him up to value his time better.
Before this, during 6th form, he worked Saturday evening in an upmarket restaurant, hard work, no breaks, good money, good fun, no cleaning! then out clubbing with the others. This enabled him to buy tech he ‘needed’ encouraged awareness, listening, speed of movement, all manner of essential skills when dealing with well heeled customers, good tips too.
Your son might thrive in this esprit de corps work rather than being locked in
a campervan alone scrubbing (emptying?) strangers shit.
Why would you want your son cleaning bogs /campervans to prove a point?
You sound as though you want to humble him.
Promulgating resentment is what you are doing.
I would also respectfully point out to anyone attempting to ‘pin the tail on
the donkey’ , that entitled is a random parameter.
