Scouting here in the Philippines
Camp Master: Hep hep!
Campers: Hoooray!
Camp Master: Hep hep!
Campers: Hoooray!
Camp Master: Hi!
Campers: Hellooooo!
Me: WTF?!
Hi! I'm Dan! I'm a... writer? Wait, Am I?
I would like to tell you... or inform you... that...
(drum roll) ... I'm new in this world!
(by the way, I love the name of this site.)
I hope that I will gain a lot of friends in here. Mwuah mwuah!
Hi and Hello! - . Webster's says that "hi" is equivalent of "hey" in Middle English--getting someone's attention. English is a strange and wonderful language.
Welcome to LitReactor :)
Hi, you spell mwah different to me. I quite like your way.
I don't know that it is slang for hello, I think they are just both greetings. Hey, hello, hi, howdy, how do you do, what's up (and the variations), hey, a (and the variations), yo; the list is endless.
Hello! Welcome to LitReactor, Dan. I think we're in the same timezone. It made me think of one of the achievements you can get. You should try the Owl one. :)
Good luck.
