Manners for Written Communication :
It is important to know what you want to say before starting to write. Make sure that you are aware that any piece of writing can be used as evidence against or for you. Make sure that you don’t write anything that could be manipulated or held against you at any time.
Write the letter with a pen in dark ink and not with the pencil. Never typewrite any social note or a personal letter. If you are not sure that your writing is readable, try writing each alphabet separately in capital letters.
Proof read the letter before sending. Especially check for misspellings and other language mistakes.
Write the date on the letter at top or at the end of a hand-written letter.
Always close a letter with a wish.
