The whole point of parenting is to produce independent, responsible, kind and thoughtful young adults with good social skills and basic life skills isn't it?
With that in mind, what are the male role models in his life like?
Do they tidy up after themselves, and are kind and thoughtful to you and other family members?
If your child treats you badly and the house like a hotel then it's important you nip that in the bud before it's ingrained behaviour.
If he didn't learn as a toddler to put his dirty laundry in the basket or dirty crockery in the dishwasher at the same time as when he was learning to clean his teeth then it's important that he gets those basic life skills learnt now.
He's probably going to be a partner or father one day and you don't want him to grow up to be one of these entitled, misogynistic and useless men you read about here on MN all the time!
Time to teach him kindly but firmly how to cook, clean, wash his clothes and tidy up on a daily basis and he doesn't get a phone or internet access until he has helped out.
This is a very important time. You don't need to shout, just be firm and kind and do not tolerate any rudeness whatsoever.
If he gets pocket money or an allowance it should be as a reward for kind and thoughtful behaviour so get him helping out daily from now on.
The best way to get all this going is to have a sit down meeting with him round the kitchen table when you are both in a good mood.
Write a list of everything that needs to be done around the house and ask him what he's like to do to contribute.
Explain it's a part of growing up to take on more responsibility. That only toddlers and babies get everything done for them.
You will find the more responsibility he is given the more he will appreciate what you do or have done for him and the better his attitude will be.
He won't take you for granted anymore.
My 12 y.o son does his own laundry, empties the dishwasher, vacuums his own room on a Sunday and makes me a cup of tea if I'm tired as he basically just follows his dad's lead.
Good luck, it will be worth it
