Lieber Herr Paehlke,\\[10pt]\rowcolor{blackit}
es tut mir sehr leid, dass ich bei den letzten\\\rowcolor{blackit} Sitzungen nicht dabei sein konnte.\\\rowcolor{blackit}
Ich habe nun für den 11.6.2002 die Einladung im \\\rowcolor{blackit} Gemeindeboten vorbereitet, bin mir aber nicht sicher, \\\rowcolor{blackit}
ob der Termin auch stimmt. \\\rowcolor{blackit}
Könnten Sie mit Frau Bach Kontakt aufnehmen und die \\\rowcolor{blackit} Sache klären? \\[10pt]\rowcolor{blackit}
Vielen Dank und viele Grüße\\\rowcolor{blackit}
Siegfried ******
