Go grocery shopping

Get a piece of paper and a pen or pencil.
Go into the kitchen and look in the pantry, the cupboards, the fridge, and the freezer.
Write down anything you are low on or have run out of.
Think of meals that you or your family likes to eat and think about what ingredients you will need to make them; then write down the missing ingredients.
Write down anything else you can think of that you want to buy.
Take your grocery bag, your wallet, and your keys.
Go to the store and buy your groceries.
Come home and put your groceries away.
Put perishables into the fridge or freezer.
Some foods don't need to be refrigerated, like eggs or lemons: put those into the cupboards or pantry.
Fold your grocery bag and put in your grocery bag holder.
