Long story short, I am returning to work next week after being out for some time on disability leave. I will be temporarily wearing a medical device that is visible. Naturally there will be people who are curious and will ask why I am wearing it, what happened to me, why I was out for so long, etc. Most people probably mean well and are just showing concern when they ask. But I am a very private person and am uncomfortable discussing or sharing personal matters, especially my health which really is no one's business. Is there a polite way to tell people to MYOB?
