The person who you trust with your life, who you tell all your secrets and is not you're boyfriend. A safe deposit box will keep all your secrets saf and is a very honest person

A person whom you trust your life's secrets with. However, a safe deposit box can not be your girlfriend/boyfriend. It is a good idea to be eachother's safe deposit box. Any one person may not have two safe deposit boxes.
Me and Ethan are best friends, he is my safe deposit box.
