You have decided to organise party for your sister. write a letter to your friend inviting her for the party. Написать письмо на английском,

Вы решили организовать вечеринку для своей сестры. Напишите письмо своему другу, пригласив ее на вечеринку.
I am turning twenty three this coming Friday. I have arranged a small party on Sunday at the Black ‘n’ White restaurant that is close to your place at 17.00 hours. I wish your presence on the occasion. The party is an informal one and is a theme based one. So, you are requested to dress based on Hawaiian theme. The party would be a great time to catch up with all our old friends and have fun just like old times. There is a dance party in the beginning and after that there is arrangement of snacks and dinner. I will also mail you the details of the party. I will look forward to meet you at the party and would appreciate if you could confirm your presence well before time so that I can make the arrangements accordingly.
Мне исполняется 23 в эту предстоящую пятницу. Я устроила маленькую вечеринку в воскресенье в ресторане «Черное и белое», который находится недалеко от твоего дома,  в 17.00 часов. Я бы хотела, чтобы ты присутствовала по этому случаю. Вечеринка является неформальной и тематической. Поэтому требуется, чтобы ты оделась в гавайском стиле. Вечеринка будет отличной возможностью повидаться со всеми нашими старыми друзьями и повеселиться как в старые добрые времена. Вначале намечены танцы, после которых есть договоренность о закусках и ужине. Я также отправлю тебе по почте подробности вечеринки. С нетерпением буду ждать встречи с тобой на вечеринке и оценю, если ты сможешь подтвердить свое присутствие задолго до назначенного времени, чтобы я смогла сделать соответствующие  приготовления.

(Напишите письмо) Last Saturday I was invited to my friend’s party. Everything was great! It was a disco party and all the people invited had to wear costumes. I enjoyed it

... very much. My friend received tons of flowers and presents. Please, tell me do have succh parties? What presents do you usually give to your friends? Does everyone enjoy parties? What was your best present you ever received? You know, I have just started reading a fantastic novel.

Dear friend,
Thanks fo your letter. Sorry I haven’t written for so long because I’ve been busy with my study. 
In your letter you asked me about parties. Well, I have parties and I like them. When I go to my friends’ parties, I usually give them sweets or chocolate, because all of my friends like sweet things. Everyone enjoys parties because there is always good music, nice people and amazing furnishings. The best present I have ever recieved was a very good book of my favorite writer. I was so happy!
Sorry I have to stop now because my mom asked me to help her.
Best wishes,
(твое имя)
