FINE

How are you?
Did you just reply with 'Fine'?
Seriously, I don' t think I can get enough of that word because the word is so often used and weighs so much. When someone gives you that word as a response, its strength always tell so much of its content and from experiences, I've gathered that the strength of this word can range from Very sharp to sharp, normal, and lastly solemn.
What does the strength of this word tell? It tells something about the speaker and here is my opinion:

Very sharp: This is often used in a conversation between disagreeing parties. A typical illustration is when a couple engaging in an argument and one of them is tired of driving one point around for the other person to understand, you get a very sharp FINE or GOOD! This word hits the other person to an instant mute state.

Sharp: This is often used when concord is about to be reached in a conversation. See the conversation below,
Girl: Let's take rice for lunch
Boy: Hmmmm, let's take rice and beans
Girl: Nooooo
Boy: Yesssss
Girl: But we ate beans yesterday, took bread and egg this morning and you still want us to take rice and beans for dinner. I don't even understand why on earth guys love beans...
(Boy interrupts) Okay... FINE! Let's go for rice.
The very sharp and sharp type are sometimes used in reply when one is in a rush. In this case, it doesn't tell much of the speaker.

Normal: This is used in absolute acceptance of an idea, in replies to close pals/loved ones. It is most often used when a person is in a happy, cool or peaceful state. It sometimes come with a smile or an emphasis. It tells that the person feels good.

Dull: This is usually below normal and you can tell that this person is not in such a great mood. There is probably something wrong somewhere. Atimes, you get this dull response when a person is just waking up from sleep or when they are tired.

Solemn: This is always basic. You can barely hear what this speaker is saying. Sometimes, he/she barely completes the word such that you need to move closer or ask from a distance if all is well cause the person's contempt is really weak.

The very sharp and solemn are extremes of acidity and alkalinity respectively. The sharp is acidic, dull; basic and normal; neutral.

Hope you enjoyed reading. Was just playing around though.
