Going out (again) with in-laws on Boxing Day and 'based on tradition' we will be splitting bill with SIL, so in-laws eat for free. As they are retired, both 'kids' have higher income, but being mortgage free, car loan free, kids free etc ILs do have more money.
Not the end of the world, but it is a biggish bill at the most expensive time of the year. What really pisses me off is that FIL abuses it. He will have 3 course, always the most expensive ones, and will always order and guzzle wine, even though he is not that keen on it and never has any at home.
AIBU to resent this? DH says just go with it, but I think he is a CF and it is making me not look forward to the lunch, which could actually be good fun.
