Is it normal to meet someone as kind as this?
When I was giving a presentation, I had a book passed around the class for further reading (and as a method for detracting attention from me). When the presentation ended and the book was handed back, I found a sticky note inside with: "You did well! :)" printed on.
I also happened to see the same person help an elderly lady across the road, offer an umbrella to a stranger and the like. She did this while unaware that I was in my car and happened to glimpse her.
Is this level of kindness normal?
