My sister doesn’t have a car. My parents live approx 70 miles from the town where we both live. She expects to jump in and get a lift and/or her partner either there on back (or both ways) every time we are both going to see my parents.
No petrol money is offered. I feel it is impossible to say no but her company is also exhausting. Can anyone suggest a polite (or humorous?) way to request a set contribution towards the lifts per journey? Or is this unacceptable? She is saving approx £30 each time.
We have also fallen out in recent years. The lift situation has been like this for over a decade.
I have a child and husband, she just has husband with no dependents.
She often wants to specify when journeys will take place or join at short notice (she has controlling, narcissistic tendencies). I have managed to put a stop to this at times but the behaviour re-emerges, and the relationship has to be managed if that makes sense.
Thanks for reading and for your advice! :)
