Dear Mike

Thanks a lot for your letter.I was delighted to read you aren't suffering from backache anymore!

I'm writing to you because I can't accept your invite to Easter time. Sorry, but I planned before Easter with my family.
Atmosphere in my home ahead Easter is good. My mother usually cooks meals and cakes. We sometimes clean our home.
Maybe You will come to us, and You will spend this Easter with my family. My mother like you very much, and She will have nothing against about this. I will be so happy if you will come.
I promise! I show You my town and all suburbs.
Give my best wishes to the family.
