„Proszę przyjmijcie wyrazy najszczerszego 
współczucia i żalu.
Wiem że nikt i nic nie wypełni już tej luki 
w Waszych sercach,
lecz pamiętajcie że nie umiera ten 
kto trwa w pamięci bliskich. 
Przeznaczenie odebrało Cię 
zbyt szybko rodzinie i przyjaciołom,
ale nigdy nie odbierze Cię 
naszej pamięci i naszym sercom.”
