Yo a mi abuela la semana pasada. (visitar)

I'm not sure if you mean for us to translate or to answer. but i'll translate as these are questions for you to answer. 1. how long has it been since you've read a book? . 2. how long has it been since you've eaten breakfast? . 3. how long has it been since you've talked with your spanish professor?

Can u give me a link to the video so i can answer your question
