Gunnery Sgt. Virgen Jenkins, postal chief, shows Rosaleah Cruz, 3, how to place her letter in the mailbox at the Marine Corps Base Hawaii post office, Dec. 12, 2013. The children from Kupulau Child Development Center received a mini tour of the base post office. They also brought holiday pictures to mail to family members. The Marines from the base post office taught the children how to stamp the official processing date on each letter and insert them into a mailbox. (U.S. Marine Corps photo by Kristen Wong)
