Hi Johanna! No sé que quieres decir aquí. Quizás... "And I don't know what to make (for dinner). After dinner, I'll probably just stay in and watch television with my grandma. (Y no sé que hacer para la cena. Después de cenar, probablemente me quedo en casa y ver la tevelisión con mi abuela.)" <-- Y disculpa, mi español no es muy bueno! :-)

She is very happy because my uncle is going to come be home all weekend.

Aquí, puedes decir "be home all weekend" o "come home for the weekend." :-)
