Material Boundaries Material boundaries have to do with your possessions. Your stuff is your stuff. If you decide to share your stuff, it’s your choice. You also have the right to determine how others treat your possessions. If you loan a friend a tool in good condition, it’s appropriate to expect the tool to be returned in the same shape. When people give you something back in worse condition, they’ve violated your material boundaries. Examples of Material Boundary Violations Using things longer than the agreed-on time frame Never returning a borrowed item
