From USPS News Link:
North Little Rock, AR, Letter Carrier Phillip Mariner was on his route when he came upon a boy sitting on the sidewalk crying. The child said his mother didn’t pick him up after school and he couldn’t find his way home because his family was new to the area. Mariner called 911 and stayed with the boy until police arrived. Mariner later learned the officers reunited the boy with his family.
