me and my family are going to tehran next week. we booked a hotel at there and we also talked with the receptionist. we are going to travel by plane and Im very happy because I really love traveling by plane. me and my father are going to exchange money today cause after we arrive Tehran were going to Brazil. my mother and my sister had already packed for the trip and theyre so happy. my father told me that I should fill out a form at the airport, so I am practicing to sign perfectly.
