     At times, you need to say thanks for a cool CD, for a favor from a fricnd, or a wonderful party. So it

is polite and kind to write a thank-you note.

     Here arc some tips on how to do it:

     ●Use a pcn,  or a nice card.  A ballpoint is also OK.  But save the excise book paper for

schoolwork.

      Write as if you were talking to the person.  Sometimes, when we're trying to sound polite, we sound

unnatural.  No: I have always wanted to own a toy panda.  Yes: I've always thought toy pandas are cute.

     ●Get it in the mail today.  It's never too late to say thanks, but writing quickly is morc politc.

     Now you know the basic rules, you can start writing a thank-yOu note:

     ●Greeting.  "Dear" is often used. Hi" is also OK.

     * First thank-you. A short sentence that thanks the giver, such as "Thanks for the great birthday gift."

     ●The details.  Describe the gift,  explaining what makes it special.  A few sentences will do.

     * Second thank-you. A sentence that says thanks again.

     * Close and signature. Say "with love", or "with best regards". Then sign your name.
