Health; Your Spanish sentence needs some polishing. First of all, we distinguish between Male and Female forms of address. Buenas Noches is thusly spelled. (A/O Buenos Noches); “Ahora, Yo “ESTOY” (Missing in your sentence. Without the (Missing) word, your sentence would come out like ; “I very tired”.; “Y voy al mi cama para duermo” is also incorrect. “Y Voy A mi Cama para Dormir”. Additionally. “Canzado”, I believe is spelled with a “Z”, instead of an “S”.
(I apologize for giving you a public lesson in Spanish, in front of all the readers/posters of “Coffee Room”.
