Acknowledge your sibling’s feelings and try to understand where they are coming from.
Selfish behavior: “I get why you’re frustrated about having to share the car. It’s inconvenient and makes it harder for you to get to and from work.”
Inheritance issues: “I understand why you feel so strongly about moving into the old house. I feel the same way too—it’s almost like our last link to Dad.”
Using a non-confrontational tone, point out how they are being selfish.
Selfish behavior: “The thing is, if you keep the car all day I won’t be able to get to my afternoon classes on time.”
Inheritance issues: “You’ve been living for a while now in an apartment of your own. Besides, John and I feel that as our kids grow up, it’s really important that we have enough room for our family.”
Appeal to their sense of familial duty.
Selfish behavior: “We picked out this car together, so it makes sense that we share it, right?”
Inheritance issues: “Remember how we sat down with Dad and went over his will? I think we should honor his wishes about how to distribute the property. After all, it’s what he would have wanted.”
Tell your sibling exactly what you would like them to do to restore harmony.
Selfish behavior: “Let’s sit down together and figure out a schedule for who gets the car when.”
Inheritance issues: “Would you be able to come over tomorrow so we can finalize the asset distribution with Dad’s lawyer? This way we can immediately resolve any questions or problems.”
