ExD I hand her a cup of coffee, she takes one sip, pauses then looks to the sky - nothing said, but still a kind of abusive rudeness if taken to excess
I’d challenge that by saying ‘Is your coffee ok?’
If the answer was yes I wouldn’t give the eye roll another thought, or I might say, ‘oh good I thought there must be something wrong with it.’
If the answer was ‘no’, I’d ask in what way it wasn’t ok, & offer to make another one.
Your DiL may be being passive-aggressive, or may simply lack the ability to be assertive enough to tell you what’s wrong with your coffee.
You won’t know unless you ask her & find out.
