you have been invited bu your friend to spend the weekend

Dear David,

I received your letter yesterday and I want to say thank you for the invitation. I have always wanted to go to farm, stay there, to see the animals. I accept your invitation and I shall come with great pleasure. I can come only on Sunday as I must finish the writing of my book. I shall come early in the morning with my father. He will bring me and then he will come to take me home. What is the weather? Should I take warm clothes with me? I am looking forward to your answer and I cannot wait to see you.

With love,

Jack
