Tune in

It’s not every day that someone is so astutely tuned in to you.

What does this mean? Is today one of those days where someone is NOT astutely tuned into me? Or is today the day that the rule is broken and someone IS astutely tuned into me? And will that person have a choice in the matter? Most days even I don't want to be astutely tuned into me and throwing that responsibility on an unsuspecting stranger is probably not going to make their day.
