So eldest in college is coming home soon

She is super judgmental of W and is angry

W really seems clueless about why which I find baffling

I have avoided intervening which has been easy because she is away

W has made clumsy attempts to call and text her to no avail

I know they will both try to drag me into it when she gets home

Any advice
