Dear(пишешь имя)! I invite you to the party tomorrow. This party will take place at 18:00, on Saturday, at my apartment. Don’t forget your fancy hat. I've already decorated the house, bought some new CD's and made small presents for the guests. We will be making sandwiches, dancing and playing games all night long! I'm sure we'll have a good time! Kisses, (пишешь свое имя)
