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.
Before the introduction of stamps, it was the recipient of mailânot the senderâwho generally paid the cost of postage, giving the fee directly to the postman on delivery. The task of collecting money for letter after letter greatly slowed the postman on his route.
