Well, we aren't like you with "Hello" y "Hi". You can say "buenos días", "buenas tardes", "buenas noches"... (good morning, good afternoon, good night...) There are also more informal ways (I only recommend them if the person you're talking about is very close for you.) Personally, when I see one of my friends I shout their names xD

Que tal?? Que tal te va?? Que tal va todo? Como te va?? Que hay de nuevo?? Buenas... Hey!! y muchas más... cada sitio, ciudad o región tiene sus propias formas de saludar.

Yo comprendo, Jacobo. Muchas Gracias. I like to keep it formal so knowing this is a plus.

*just one thing, it's onda not honda..Hay otras formas muy coloquiales de saludar tambien, que se usan en Honduras y México (no se en que otros países) como ser "Qué Pedo?" (Literally "what fart?") but it could be considered very rude if you greet older people like that, so you'll have to be very close to the person you're greeting. Im not trying to be vulgar, just tryin to explain an Idiom.. lol

¡Gracias, Obando! ¡Using these will be fun!
