I am the 24/7/365 caregiver for our parent. However I have noticed over the years, they totally "drop" me when they receive a phone call (or rarer yet, visit) form a far out of state sibling.
It has even gotten to the point that they will give valuables away to these siblings, their spouses, and their kids, when they have NOT given me any valuables.
It's really frustrating, and isn't this sort of unethical for these siblings, to me it seems they are taking advantage of this really weird behavior.
What can I do?
