¡Hola amiga! Hoy te explicaré que podrás hacer en mi casa. En mi casa puedes ver la tele, hacer los deberes, también podremos hacer fiestas de chicas con mis amigas de Costa Rica. Si no te he dicho nada aún, van a venir también unas amigas mías de Costa Rica, sí quieres te las presento cuando lleguen. ¡Estoy emocionada de que vayas a vivir conmigo!
I translate the monologue in English for you to understand:
Hi friend! Today I will explain what you can do at my house. In my house you can watch TV, do your homework, we can also have girls' parties with my friends from Costa Rica. If I haven't told you anything yet, some friends of mine from Costa Rica are also coming, if you want I'll introduce them to you when they arrive. I'm excited for you to move in with me!
Remember that to express desire or uncertainty we must use the subjunctive mood. In this case I have used the subjunctive because, I suppose, her friend is not living in the house yet, but she is explaining what she will do when she moves in with her.
