Hi, Linda! Thanks for your email. How are you? I’m doing my homework. How boring! All the family are here and they are busy too. Mum is in the living room, she is making some phone calls. Dad is working in the garden — it is hard work. My little brother Tom is helping him — he is planting some flowers. My sister Zoe is having a good time — she is playing games with her friend. What are you doing? Have you got any plans for Sunday?
Write back soon.
Love,
Rosie
