At one point, I was taking dancing lessons at the stake house.
One evening, I said to a girl who was also participating, "Hello <name>—it's nice to see you!" and she replied, "You always say that it's nice to see me when you greet me!" and I said, "Well, that's because it is." And it was: I really did be happy each time I saw her; it wasn't just a phrase.
(And yes, that past sentence is probably ungrammatical, but "I really was happy" doesn't fit my mental model of the sentence.)
