Hello, dear Emma!
How are you getting on? Haven't heard from you for ages. Why  didn't you write me so long?
As for my family we are very friendly indeed. We are five: a mum, a dad, me and my younger twin sisters. They are also annoying sometimes like your brother, but I think it is just the matter of their age. I sometimes spend my free time playing with them. You know my mum is a housewife so she spends most time with them. But weekends we spend all together. I like this time because our father also joins us. We usually go to the country or to the seaside. We have a lot of fun together.
But what about you? How do you spent your weekends? Do you have a go with your best friend Katty or with your brother? Is your brother much younger you or not? Have you anything in common with him? Anyway I wish you to get on well with him.
So I must go.
See you. Bye.
