Nursing pet peeve: thinking out loud

You know the type. You're in a pod doing your work and your pod mate is reviewing the chart.

"They didn't chart the foley?" "The doc put in a cardio consult at 9 AM." "Where is her cbc?"

Sitting beside this person, my natural people pleasing activates and I can never figure out if they're wanting me to respond in some way. Should I ooh and awe or make non-committal grunts in solidarity?

Anyway, it's fairly harmless but I still internally groan whenever the murmuring starts.
