FIL lives a few hours away, and during half term we’re going to visit him. DS1(16) asked if his friend could come, DP said yes and we thought it was all sorted. We told FIL today (as FIL was talking about talking us all for a meal) and he said that it’s meant to be a family visit and he doesn't want to take the friend for a meal.
We will be staying in an Airbnb so we didn't think it would be an issue for him and DS has said he and his friend will probably go somewhere together anyway.
Am I BU to think this isn't up to FIL?
