Our reading
An editorial interpretation.
The saying links the depth of disappointment to the depth of love behind it. A painful letdown becomes evidence that something mattered greatly, rather than simply an isolated bad feeling. Read this way, the contrast gives disappointment an emotional history rooted in attachment and expectation.
