Hello everybody!

Good morning! or good afternoon! or good evening! (not good night 'cause it would mean that my writing would be too boring to read).
I wanted to spend my time, and your time if you read this, to show my incredible skills to greet in inglish  English. I think it's an essential way to learn the basics on social communications.
Really. I only want to say hello, or hi, if you're able to consider me as a friend or as a simple stupid-but-nice person.
I have read that "hello" is a more informal form (I  i apologize for the word pun), but more often the more common form is also used also to answer, for example, the phone.
Just said this, i'm not sure about the conclusion of this meaningless writing.
Maybe 'goodbye'? but it seems to be too dramatic as a greeting. It isn't 'Goodbye' the shape to end everything? Like 'goodbye!', and then he is dead.
Maybe more simple 'See you', or 'See ya' in slang. It could be fine to salute someone who  I  i have already meet met. And if i didn't have meet  I hadn't met him or her?
No, a better way to concude conclude is 'bye' (with a long 'y' pronounced in my mind) or 'bye bye'. The last one always remembers reminds me of  a Japanese teen girl who sais says that with her young youthful voice. Too bothersome I think. Or simply I need to stop seeing anime. (?) (Not sure what this means)
I apologize if I offended someone, for example a Japanese girl, it wouldn't be wasn't my intention.
What I want to learn, for first, is to salute, or to greet, or other words to say the same thing in inglish.

What I want to learn, in the first instance, are all the different words one can use to salute or to greet in English.

So, now i don't want to say goodbye. Tell me how to conclude this piece.
Ciao! ;)

How about Cheerio.   or   See you later     or   (very modern!)  Laters!
