Complete Conrad's email with have to, has to, doesn't have to, or don't have to.

Hi Dexter, I'm in Bolivia for six months with my mum and dad. I don't go to school here — I have to learn Spanish! There's a teacher at home instead. My parents don't have to worry about me — luckily they don't have to work at the moment. They (1) don't have to go anywhere. At home, school starts at 9:00 in the morning. I (2) have to do lessons in Spanish. But I (3) don't have to take any exams here. My teacher leaves at 5:00 p.m. when my mum gets home. My dad often (4) has to work late — until 8:00 p.m. or 9:00 p.m. So my school day is very long — but I (5) don't have to do any homework, so that's good. Please reply soon. You (6) don't have to write a long email. A short message is OK. Bye for now, Conrad.
