Our first and fifth graders are happy about the replies to their airmail. Greetings, attached to ballons, that were sent by them on their first day in school flew far across the country. Families in Wietzendorf in the Lüneburger Heide wished them luck. So did families from Klötze in Altmarkkreis Salzwedel and from Peine and Lehrte in the South-East of Hannover.
