Invitation

hello friend i just got an invitation letter from my friend
to attend his birthday at saturday 4th desember.
do you know how to make an invitation card or making an informal/formal invitation to others?
how about we discuss it?
what do you know about invitation?
it's use to invite some one right
then what is the meaning of invitaion?

    Invitations are very common in our daily life. They can be divided into two 

categories: invitation card and invitation letter. 

   An informal invitation resembles a business letter. When sent from a business 

office, the letter is sometimes keyboarded on executive stationery, which is smaller 

than the regular business letterhead. Although many formal invitations are 

handwritten, especially for smaller groups, formal invitations generally are printed 

and follow formats found in etiquette books 

  Wording of invitations should be conversational, as though the writer were 

extending the invitation orally. A general invitation should be cordial and sincere, 

while a formal invitation should be less personal, written in the third person. 

  Often formal invitations include "RSVP" and a telephone number. The RSVP 

notation means "Please let us know if you plan to attend." It informs invited guests 

that the host is expecting an immediate telephone reply to facilitate plans for the 

event. If an invitation includes "Regrets only", it will require a reply only if the 

invited guest cannot attend. 

Invitations are written in the deductive pattern and are relatively short. Either 

kind of invitation, however, must do three things: 

•Invite the reader to the gathering. 

•Offer a reason for the gathering. 

•Give the date, time, and place of the gathering.
