Mil lives in central London and regularly goes away for long periods at a time say 6 weeks. Because of road maintenance etc she feels she can't risk leaving her car in the roads surrounding her home for fear it will be towed away if they do any work on the road.
So every time she goes away (at least 3 x per year) she brings the car to us and leaves it in a local station car park that doesn't charge. We are just under an hours train trip from London. She never gets the train always coach as cheaper then we have to collect her from a local town and take her to pick her car up. She has just refused to get train directly to the station to get her own car btw.
We do not have room on our drive for her car btw this has been a past battle.
She is highly demanding about this and expects everyone to drop everything when she decides she wants to pick it up. Today she has just phoned demanding we arrange to pick her up tonight to do it having arrived back yesterday. This is not convenient we both work and have 3 children who include 2 school age with after school activities tonight plus a toddler.
To clarify no she never combines it in anyway with seeing her grandchildren, no she never has or does help us in anyway. Her standard line is "it's our duty to do as she wants".
So AIBU to be a little miffed and think she should pay airport parking like the rest of us or leave her car at home.
Also her other child lives in London and could surely check on said car occasionally? ( she does help other child regularly with child care also despite ignoring our children)
Or I'm a complete cow? (Probably but seriously she has been really rude today telling us her car is more important than our children's clubs)
