Your first apartment will teach you that groceries cost more than you thought and nobody refills the toilet paper but you.

Two facts land in the first month and neither is in anyone’s advice. Food costs roughly double what you estimated, because you were only ever pricing the interesting items and not the oil, the bin bags, the washing up liquid, the milk you get through. And every small restocking job in the place is now assigned to one person.

So price a real week now while somebody else is paying: write down everything that gets used in your house for seven days. Then add the dull items to your own list. Both the number and the list will be bigger than you think.
