My neighbour has just called my DP and asked if he could take his children and mother to the airport next week as they (neighbours) will already be away. It's a 120 mile round trip. However the neighbour has asked to use the 7 seater. Which is my new car I've had less than 2 weeks. It's not brand new but it's new to me and it cost me a lot of money. He agreed to this on the phone and then came to ask me and I've said no. I don't want my family car being used a taxi. My partner thinks I'm being unreasonable. Do you?
