The third sentence always ruins it

I was just watching someone explain a spreadsheet pivot table to a client, and the moment they said 'and then you just drag the field here' — I knew it was over. The third sentence is where people either lean in or check their phones. I’ve seen it in courtrooms, on Zoom calls, even in quiet moments with my sister. It’s not about clarity. It’s about the unspoken question: do you actually care? And usually, no. But I still watch for it. Like a ritual.
