DH is going up north tomorrow to visit MIL with our dd1. I'm at home with dd2 who's ill. BIL and SIL are going too. They want to go on same train but have just texted to say they're upgrading to first class. DH can't afford to upgrade (makes the day trip ridiculously expensive) so now faces the prospect of meeting them at station, getting on train, travelling separately and then getting bus at other end to MIL's house. What's the point? Why can't they just sit in standard with dd1 and DH? I know it's not major in the grand scheme of things, but why do they have to be such pains?!
