The traffic light as a traffic rule in the home office
Within a family, the home is always busy. Working at a desk often requires increased concentration. You don't want to be disturbed in this phase. A self-made traffic light that is attached to the door to the home office is helpful here. With “red” there is a strict entry ban, with “yellow” family members should only be disturbed if it is of great importance and with “green” children are allowed to come in with irrelevant questions or explanations. Probably the color “yellow” is preferred and safe at home domestic peace, whereby "green" and "red" must not be allowed to fall under the table, so that the system can be used in an understandable, credible and helpful manner.
