The flip side is that they sometimes genuinely want to help. As you say, be respectful.
My elderly neighbour (who I saw maybe twice in a decade) had her daughter visiting, and the daughter came by and suggested I might like to change the dressings on her mother’s ulcers because I’m “used to looking at gross stuff.”
I’m a radiographer. I’m pretty much useless in every situation unless someone has a a high field magnets and wants pictures.
Right, I am speaking more about close relationships where they’d offer help without you even having to ask, not some long-lost friend that you only ever bother when you need their medical opinion.
