Greetings

"Good morning starshine, the earth says Hello!"




Social Norms: 
Good Morning: 12am - 12pm
Good Afternoon: 12pm - 6pm
Good Evening: 6pm - 9pm
Good Night: 9pm - 12am


The social norms do not make sense. I usually say "good morning" until 2pm because that is the time when I am just fully awake, then I crash at 2pm, and would if I actually did, say "good afternoon" until it gets dark. I would assume that most people send off a "good night" once it is dark. 


I believe that the proper greetings should be based on sole observation of the position of the sun in the sky.


My only question is why "morning" is for an entire twelve hours, and afternoon, evening, and night are morphed into another twelve.


And, why can't we just say "Good Ante Noon," and "Good Post Noon?" and then just change the subscripts to AN and PN.


OR, why not go with the original, "Good Ante Meridiem" and "Good Post Meridiem?" [AM and PM]


Why be so particular?
Let's get specific, shall we? It is 11:59am, I say "Good Morning!" 
                                          It is 12:00pm, I say "Good Noon [on the dot]!"
                                          It is 12:01pm, I say "Good Afternoon!"


So complicated. Just observe the sky. We should say "Morning!" all day long because "morning" sounds a lot less awkward than "and a good afternoon to you," and a lot less creepy than "and especially a good evening to you." 


Maybe we should just take out "evening" all together and consider the entirety of "night" the evening. It makes more sense logically, then, to say "Morning" until noon, "Afternoon" until dark, and "Night" upon darkness. I presume these masters presumed "evening" would be the transition period between "afternoon" and "night," but if that is the case, then wherever did the transition period between the darkness of the morning and the light of morning go? 


....


which brings me back to my first question. ["My only question is why "morning" is for an entire twelve hours, and afternoon, evening, and night are morphed into another twelve."] Perhaps the fallacy is not in the later hours of the day, but rather it is in the beginning. [and don't tell me I can use "dusk" or "twilight" because those are interchangeable too.] If we are going to be so specific people, then we must continue in our specificity. Good Luck to all.

Well, to counter everything I've just argued, if Truman says it, then it must be right:

"Good morning! And in case I don't see you: good afternoon, good evening and good night!"
