At work today me and a coworker were on lunch together and I was asked what I was doing for new years. I told her I was going to see my grandmother and her reply was "aww thats cute" followed by "youre going to chill with your grandmother"

It got me thinking about the context of "aww thats cute". Im sure in general this is considered a death sentence and in high school I noticed it was while being a nice guy. "Aww thats cute" when complimenting a girl is rather negative. But what is TRPs take on this phrase in other contexts like a man playing with children or taking care of an elderly parent, or any other scenario?

Edit: Maybe a better way to ask is what is TRPs views on this phrase for evoking emotion
