Good

The word “good” has many definitions, including but not limited to:
* Positiveness (a generally positive connotation)
* Negativeness (a generally negative connotation)
* Indifference
* Go fuck yourself (similar to indifference, but more malicious)

A prime example of a usage of “good” comes from the following exchange:
“How are you doing?”
“Good.”
In this situation, “good” can mean any of the last 3 meanings above.
It cannot mean “Positiveness” as if it did, the above exchange would be grammatically incorrect (the correct usage would be “well”).

An example of “Positiveness” is:
“Who’s a good boy?”
Or
“Who’s a good girl?”
This in fact is the only correct usage of the positive “good”. This is because the only good in this world comes from dogs and other pets.
