No lo se o yo no sey?
I'm hearing many people say one or the other or both, can anyone shed some light on this for me? Which one am i better of using?
Gracias y adios!
Theres also: yo que se which is used when you have absolutely no idea (and sometimes when someone asks you something that you dont know or care to know about). For example: por que no ha venido Julia a la feria? ( why hasnt/didnt Julia come to the party?) / yo que se. Me da igual. No me cae bien. ( how should i know? It doesnt matter to me. We dont get along well).
