[header] How to mail a package without your parents knowing [title] Before you do anything, you need to get a box to mail your item in. [step] Find an extra one lying around the house, ask a friend or relative if they have one, or buy one. [substeps] If you need to ask your parents to buy you a box, say you need it for storage or a school project.
