Some things we choose to share with our family/whanau, friends, and acquaintances. Such things may include: our successes, family members’ successes, holiday plans and even just small everyday matters. Some things we cannot easily share, because there may be a stigma attached to them.
A stigma is a sort of secret which causes us shame and makes us want to conceal or hide it. This is called a “concealed stigma”. So maybe you have a concealed stigma—so far so good—why would it not just be an excellent idea to keep such details to yourself, end of story?
