What Is the Difference Between Complaining and Venting?

A question like this cannot be answered without definitions. You can't defend or condemn a word like complaining until you know what the reality is that the word is referring to. When that's clear, then you're in a position to say that reality is good or that reality is bad, sinful. Cina comes close to giving me a definition of complaining and venting. She does it with two illustrations rather than two definitions. But if we work backward from her illustrations, we can arrive at definitions, at least partial definitions.
