Teenagers, when you finally reach adulthood and get a job, spend your first wage on a mobile phone far nicer than anything your parents could ever afford for themselves. Then request that they pay for your haircut/new shoes/work trousers. When they react in horror, point out that you never ask for much, refuse to accept that they pay to keep a roof over your head/food in the fridge etc, and point out that because one of them bought a top for a fiver last month, they are forever spending money on themselves.
Treat all requests to contribute to the running of the house with disgust, as you have a laptop to buy next month.
Also remember that by working 16 hours a week that you will be far too busy and exhausted to do any housework other than washing your favourite top on a daily basis. This will count as "doing the laundry" and constitues your entire share of household tasks.
Complain loudly that everone is always in a bad mood in this house.
