First of all, I just want to say that I genuinely love my husband's family and get on well with them. However, their attitude towards money and doing favours for one another is really jarring and makes me feel uncomfortable.
When it comes to meals out, holidays, petrol money etc every penny is accounted for and split to an almost ridiculous degree. It's confusing as they are all high-earners. For example, yesterday my brother-in-law wanted to transfer me money for giving his mum a lift to the doctors and buying her a snack+tea. Obviously, it's one of those things you do to help your loved ones out and not for financial gain (there have been far more extreme e.g's). I know there are worse things to worry about but I feel it has a cheapening effect.
I grew up with a family that had a completely different attitude, the idea of a child transferring their parent's money would horrify my own family. We do favours for each other and yeah sometimes you are out of pocket but so what? It will likely work itself out in the long run anyway.
I just have no idea how to adjust to their way of thinking. It's not the kind of relationships I want. AIBU to ask what you would do.
