teachers: "good morning" or "hello"
friends: "hi" or "hey there"
strangers: "umm.. hello"

"hi what do u want"

"Oi!" is how I greet peeps. If I'm unfamiliar with somebody, I speak very formally.

transformice: "suprise moddafakka"
irl: "hello- gSDKGJMSGHSMNH"

When I greet somebody I usually say "Yo." or "Guten tag<3!"
if you ask, yes i am german.

".....-runs away-"

Say a cute "Hi!" and wave.

I just say "Hi." or avoid them. Even if its my friends.

Or alternatively kick'em and sacrifice them.

If it's someone I know then I have a bunch of ways to greet 'em, like hi, hellr, how ya doin' and 'sup bro. 'Y know, stuff like that.

If I don't know them then I would only say hi.

Well in my house my and my sisters scream "HALLO!" and my friend "Herro" and to everyone else *shy smile*

usually i say "good morning" or "hello" to my friends since i first see them in the morning
i use "hey kiddo" and "hey there" with everyone else
