Doing all the laundry
As a babysitter in your teens or twenties, one of the big perks can be spending time in houses that are much more impressive than your own. If you have a friendly employer, they might say something like “make yourself at home,” before they head out for the evening. They usually mean, grab a can of coke from the fridge, or choose what you want to watch on the TV.
They generally don’t mean use the washer-dryer to get all of your laundry done using our electricity. They definitely don’t mean that you should feel comfortable enough to strip down and throw the clothes that you’re wearing into the wash as well, and then sit naked on our sofa watching TV. I feel like that should go without saying.
