Could a good friend of yours use a pick-me-up? Might someone you haven't connected with in a while appreciate a friendly hello? Why not give that special someone's mailbox, too often stuffed with bills and junk, a big hug?! Nothing brightens a day like a heartfelt message from someone who cares. Whether you're sending mail to a close friend, family member, or coworker, let them know they were the most important thing on your mind today.
