What a difference a border makes: on one side of an invisible line, food; on the other side, none. On one side, peace. On the other side, war. On one side, quiet in the sunlight. On the other side the dangerous chee-eep, chee-eep, chee-eep, that was not birds, the BANG! of shells, the whine of sirens, and the bursting of bombs over crowded cities.
