Trying to catch a baby duck is like trying to hold water, or happiness, in your hands. They seem to be Schrodingers ducks for how rapidly and unexpectedly they move.
And an adult duck? They sometimes pet you back! I kept ducks for a while and one would regularly preen my fingers as though they were feathers.
Ducks can be happiness.
Volunteer firefighters (USA), those guys do important work and do not get tax money.
