If children will be receiving holiday gifts, they should be getting ready to write their thank-you notes.  A great way to begin is with SpongeBob Squarepants — I mean SpongeBob Mailpants — who is teaching children to write letters and postcards with a great new website.  There are free SpongeBob postcards at the Post Office for you to pick up and mail the old-fashioned way.  Parents can pick up a card to send to children to teach them the first lesson of letter-writing, the pleasure of opening up the mail to find something special just for you.
