My pil are very young. Mil had dh when she was 18 and his brother when she was 20. Fil is 5 years older.
Fast forward 50+ years and the pils are in their early/mid 70s.
They have asked that dbil and dh go with them on a trip to Europe next summer for a few days.
The wives and grandchildren are not invited this is fine with me, I really would not want to go and dh has agreed with a heavy sigh because he does not want to go either.
However, I just cannot imagine myself X years into the future expecting my adult dc to accompany on a trip abroad which is important to me (but not them) when I am still solvent, of sound mind and body, and have a partner to accompany me.
Or perhaps Iabu.
