A farewell speech, formal or informal, is often necessary. It may be delivered at the dinner table, or at other places such as the airport,seaport, railway station, etc. The contents of the speech depend very often on the special features of a specific group, but the speech is usually flooded with beautiful memorries and good wishes.
