In the United States, people often invite friends to dinner, parties or coffee. People often say, would you like to come to dinner tonight? We have a party on Friday. Can you answer an invitation? They say thank you and accept it, or say sorry and give reasons.
What people say is like an invitation, but it's not a real invitation. For example, please come and have a drink. When can we have lunch together? They are not really invited because they don't mention the date or time.
They just indicate that the person is right In an effort to be friendly people, they are usually quite sure that it will be great or good, thank you so next time you hear the invitation, listen carefully.
Dear Henry: Thank you very much for your invitation. I am very happy to be one of the limited guests you have invited. I really want to join you.
However, the most unfortunate thing is that we can't get your kind invitation on the same day that I invited John to bring a gift. Please accept this letter to express our congratulations on the party and wish your family a happy meal, Jane.
