My MIL lives next door. In the past I have invited her and FIL and GFIL aged 93 over, she has declined and says it is because GFIL gets settled and doesn't like moving .Fair enough, at that age you can do what you want. However last year SIL invited them all up (1.5 hours drive away). MIL said Oh well haven't told GFIL yet but he doesn't mind, he'll do whatever.I asked what made it easier for him to move 1.5 hours drive away(for the day)compared to next door and got no straight answer. This year I get the same story. I just wish she would be honest- are my kids awful compared to their cousins? Does she not like the food? Do I give in and go there for lunch again or dig my heels in and have seperate lunches next door to each other?????? AIBU to want to know the real reason
