A fancy excuse for saying something nobody wants to hear but everyone already knows

I don't mean to fling olives on the floor but your dad still lives in the fridge.

I don't mean to fling olives on the floor but your life is still in the 70s.

I don't mean to fling olives on the floor but your dog still barks at your mom.
