Today I went to see my OB/GYN for a follow up appointment. I left 3 hours after my appointment time. Although I had the first appointment after lunch, he had to leave to go deliver a baby so I went and ate and came back and waited some more (total wait time about 2.5 hours).
When he (finally!) came into the room, I said "welcome back."
He got the biggest grin and said "you just turned my whole day around."
I said, "It sounds like you're kinda having a rough day."
He said, "I've had the worst month!" and pulled up a stool and told me all about it (with me still sitting there with no pants under a paper sheet ) He ended with "you are wonderful, you're the kind of patient that makes doing this worthwhile."

Wow! All I said was welcome back and I listened and what an amazing impact.
