Lia and Farah are talking about their yesterday activities in the break time at school.

Lia: Hi Farah, the weather is so nice, isn’t it?

Farah: Yeah … but I feel unwell and tired because of my yesterday activity.

Lia: What did you do yesterday?

Farah: My mom asked me to visit my grandma. We didn’t see her for a couple of days.

Lia: I see, she was longing for her pretty granddaughter. Did she live alone?

Farah: No, she didn’t. My grandma lived with my uncle. How about you? Where did you go?

Lia: I stayed at home. I cleaned my room.

Farah: It’s a good activity. I’m sorry, Lia, the next lesson is English and I forget to bring a dictionary, so I have to borrow it from the library. See you.

Lia: Okay. See you later.
