I'm growing tired of easy things. (1.10.153)
That's the thing about easy: it's relaxing at first, but then it becomes boring. Warm Bodies shows us that too much "easy" can actually be deadly. That's why our vacations are never permanent.
"No one in this place really looks at each other anyway." (2.3.87)
