Intrapersonal communication serves several social functions. Internal vocalization, or talking to ourselves, can help us achieve or maintain social adjustment. For example, a person may use self-talk to calm himself down in a stressful situation, or a shy person may remind herself to smile during a social event.
The capital of Chile is Santiago
I think it’s voy....because voy means
“I’m going, I go, I arrive....etc”
So your sentence is...
Yo no voy llegar a las de la tarde.
Translation:
“I'm not going to arrive in the afternoon.”
