My stepmum took this one step further. Using the powers of tinternet, she truffled out relatives in the American Mid West, made contact with them, then arranged to visit. They could have been murderers, or pig sexing hillbillies, as I warned my dad several times. Turned out they were just boring. And mildly irritated by the visit too. So they inflicted one back, which iritated my folks. So they inflicted another one back. Repeat to fade.
I think sometimes these things are best left alone.
