I invited a friend and her DC to join us on a trip to Scotland. It’s quite a long way from where we live. We have a seven-seater so the two families fit perfectly in the car. I never said we should share the costs of petrol or parking and I initially thought this would be fine. DH said we should ask, but I insisted we shouldn’t. These were costs we would have anyway, I said, so no need to ask her to contribute. But I’m now left with an uncomfortable feeling that she should offer to pay her share and then it should be down to us to decide. Actually she kind of did that. In the car, she said she would contribute with the petrol. But after a few hours driving, we had to fill up the tank and no additional word from her. In her place, I would undoubtedly have offered to split costs and insisted if needed. We visited quite a few places so we also spent a lot on parking (around 40 pounds in total). I organised the whole trip so I ended paying some of the costs in advance. She paid me back but slightly less than it was due (77 became 75). I know I’m sounding very petty, but maybe I am! About a year ago, they came along on two day trips and she never offered to contribute. In one of them, she offered to split in two the cost of lunch when we always pay more as we have one additional adult. In the other, she bought the kids ice cream. So it’s not like she’s unaware we are partially subsidising her trips. Especially considering this latest, more expensive one. She has more disposable income than we have by the way. It’s been a week since we’ve been back and today she cheerfully asked me where I would I take them next.
