Your colleagues are regularly berated by a man who lives across the road from your workplace.

When they park outside his house, his rubbish isn't collected and he gets very angry and sometimes puts the full bin on the bonnet of their car.

No one knows that the angry bin man is an estranged relative of yours.

Do you have to tell your work colleagues you're related? And are you obliged to say something to your relative or any other family member about this behaviour?
