Buster is part of the problem-solving group known as the Super Sleuths along with Darby, Pooh and Tigger. Though oftentimes he seems to be only tagging along, his nose and his curiosity have proven an asset in many of the groups' cases. Darby also loves him as a loyal companion who is fun to play with.
Noun[edit] mailman â(plural mailmen) ( 1 US) someone (implied male) who delivers mail to, and/or collects mail from, residential or commercial addresses, or from public mailboxes.  The gender-neutral letter carrier is sometimes preferred.
Each region around the world entered the development stages of mail at different times throughout history. Rome is claimed to have the first well documented postal service which arose under Augustus Caesar around the time of the birth of Christ (Wikipedia, 2007). In North America, the mail system began in the late 1600s when mail was carried by friends, merchants, and Native Americans. It was in 1673 when Governor Francis Lovelace created a monthly post between New York and Boston. Later, in 1683, William Penn opened Pennsylvaniaâs first post office.
