Think back to the beginning of Night when Elie was forced to live in the ghettos of Sighet.  Remember what types of things were taken away:  Freedom to leave the five block area; ability to walk around without wearing the Star of David; opportunities to interact with friends in Sighet who weren't Jewish. 

The poet Pavel Friedman attempts to capture how this affected his feelings but focusing on one thing that the ghettos took away from him:   Butterflies.

"The Butterfly"

by Pavel Friedman

The last, the very last,
So richly, brightly, dazzingly yellow.
Perhaps if the sun's tears would sing
against a white stone

Such, such a yellow
Is carried lightly 'way up high.
It went away I'm sure because it wished to
kiss the world goodbye.

For seven weeks I've lived in here,
penned up inside this ghetto
But I have found my people here.
The dandelions call to me
and the white chestnut candles in the court.
Only I never saw another butterfly.

That butterfly was the last one.
Butterflies don't live in here,
In the ghetto.
