Dear Tanya,
Thank you for your letter.
You asked me to tell you about my jobs at home,so i dont do housework everyday.As for me there is no need to do it too often.It takes lots of your time if you have a big house or flat.
By the way, what do you think about tree planting?How can it help our world?And what you need to plant a tree?
Unfortunately, I’d better go now because i`ve got to feed my kitten.Drop me a line when you can.
All the best,
Helen(Elena)
