I will treat my DPs job commitments as a nuisance, as all the job does is pay for food, housing, etc.
I will insist on our family moving to a remote location then complain about spending money on travel.
When I'm on my feet I will make a huffing noise so that everyone knows JUST HOW BUSY I am.
I will sneer at anyone who spends money on things I cannot afford.
I will make only basic dishes myself, but when someone else is spending time cooking I will say really helpful things like "I would cut that a bit thinner" and "that needed more dill". I will also leave my dishes for someone else to put in the dishwasher to ensure consistency.
I will take credit for stuff when I wasn't even there - i.e. "We decorated the house ourselves", or "It took us all summer to paint this fence."
When my DP hangs clothes up to dry, I will be really helpful and rearrange them for no reason.
I will insist I am too busy to run errands for other people, while at the same time assuming my DP has access to a wormhole allowing for two hours worth of tasks to be done in a 30min lunch.
Other people's interests and hobbies will be treated with disinterest, if not outright contempt - however, my own are so crucial as to require others to commit their time and energy so that I can enjoy them.
I will repeatedly fart on the couch, but get indignant if the bathroom isn't springtime fresh.
