Barrow the mail

I think you meant to say "borrow the mail"!

"Borrow" means to take something from someone else with the intention of returning it later. In this case, if you borrow the mail, you're taking someone else's mail with the intention of returning it to them later.

However, I think there might be some confusion here. It's not common to borrow someone else's mail, as it's typically a personal and private item. Instead, you might be thinking of borrowing something else, like a book or a tool.

If you could provide more context or clarify what you mean by "borrow the mail", I'd be happy to help you out!
