Hi Lisa,
Thanks for your email. I'm glad you can come to stay.
On Saturday, my mum has to go to work, so
I ¹ have to cook dinner and look after my little brother but we can go out later. We ² don't have to get a bus - my dad can take us into the town centre.
Usually, I ³ have to come home at 10 p.m. but, because you're here, I ⁴ don't have to be at home until midnight. What time ⁵ do you have to leave on Sunday?
My mum ⁶ has to go to work, so she can cook us a nice Sunday lunch and then take you to the railway station.
Let me know. See you soon.
Rachel
