How if it's sixty degrees outside at night in the summer, we think it's kind of nice out. But on that same summer night, if you walk into a restaurant that sixty degrees, we think it's freezing."
Hermione shrugs. "Humidity outside -- that plays a factor. And it's expectations. We know we're exposed to the elements outside. Inside, we expect to be more cocooned."
"Sort of like people." At Hermione's confused look, Cho continues. "People are harder outside, their facade, because they know they are exposed to the world there. But they don't let people in easily, because they want to be cocooned there. They want to feel safe, at ease -- not like they have to prepare for the next storm or drop in temperature. You know?"
Interesting way to put it
