On the first day of Rosh Hashanah, the custom of tashlich is to throw bread into a body of water, casting your sins away. (When no natural body of water is available, a well or even a bucket has been known to do.)
A passage from Micah is recited:
What god can compare with you; taking fault away,
not cherishing anger for ever
but delighting in showing mercy?
Once more have pity on us
tread down our faults
to the bottom of the sea
throw all our sins.
Micah 7:18-19, Jerusalem Bible translation
Fault, crime, anger, sins. Ourselves and others. Pardoning, mercy, pity. Hard for ourselves and others. And as delightful as ducks and fish eating bread on the lake.
