Dear Molly,

I invite you to my Halloween party at the big old house on the outskirts of the our town at 6 pm. tomorrow. There will be a lot of creepy sweets and drinks, as well as interesting games, entertainment, dancing and singing. There will be many children and adults and also guys from our and other classes. You can come with your parents, relatives or your friends. Put on a beautiful costume of your choice and come. For example, my costume is a bat with long black wings.I hope you will accept my invitation.

We are waiting for you.

Please don't be late.

Till toworrow. Goodbye!
