Hi, Mariam! I'm at the community centre now. I usually work at the library on weekdays, but today I'm helping here. My brother Reza is putting chairs in the main hall, and my friend Tara is checking tickets at the door. The small hall has 30 seats, but the main hall has 80 seats. The main hall is bigger and more expensive to rent. We were here yesterday, too. The centre was closed in the morning, but it was open in the afternoon. Reza moved the tables and I cleaned the rooms. Tara didn't work yesterday because she was ill. Tonight we're getting ready for a music show. See you, Niloofar.
