Dear Lucy,
I was very glad to hear from you. I
haven't written for ages because of my school activities. It's a pity that you were ill last week, I hope that now you got well and fell better.
I would like to invite you to lunch at my place next Sunday. I think you will like to spend a day near the forest and a beautiful lake, to swim, to sunbathe and to comunicate with my friends and parents.
Please tell me if you are able to come by calling me at _________(номер телефона).
I am waiting for you on Sunday 11a.m.
Best regards,
Luckyguy
