Cuckoo birds are sneaky: they lay their eggs in other birds’ nests.
Sometimes the cuckoo egg is noticed and pushed out of the nest; sometimes the other bird ends up feeding and caring for the baby cuckoo.
At my last BBQ a person brought his uninvited hungry A.D.D. kid and didn’t supervise him.
The kid snatched and ate big platefuls of meat and rampaged through my place.
Next time I won’t invite the cuckoo to my nest.
