Quién organizó las llamadas Fiestas Modernistas?

hola, mi nombre es yo tengo hermanos y hermanas. mis padres celebretamos navidad juntos.

fill in the balnks and add a couple of remarks and you should have it!

si no tengo dinero necisto _911 para hacer una llamada   english: if you dont have money call 911

ah, so ustedes and nosotros are my 'go-to' if i am using spanish mainly in the states? interesting, but still slightly confusing, haha."

it seems that you are a little confused about subject pronouns. yo=i, tú/usted=you, nosotros=we, ustedes=you(plural), ellos/ellas=they.

in the case of vosotros, it is an informal replacement for "ustedes" in spain. similar to using "you all" in english.

even though it is not generally used in conversation outside of spain, it is used many times in literature. i would suggest having at least some familiarity to that form, at least to recognize what it is.
