When you go marketing, bring the groceries home in a paper sack instead of a box.

The statement you mentioned seems like a suggestion or a personal preference for using a paper sack instead of a box to carry groceries home from a shopping trip. Paper sacks are an alternative to plastic bags or reusable grocery bags that can be more eco-friendly and biodegradable.

If you're wondering why someone would suggest using a paper sack instead of a box, it might be because paper sacks are lightweight and easier to carry. Additionally, they can be folded or compressed, making them more convenient for storage or disposal after use.

However, it's important to note that when it comes to choosing the right packaging for carrying groceries, personal preference and convenience can vary. Some people may prefer using reusable cloth bags or even boxes, depending on their individual needs and preferences.

Ultimately, the choice of whether to use a paper sack or a box when going grocery shopping depends on factors such as availability, environmental concerns, cost, and personal convenience.
