Voici l’expression idiomatique de cette semaine :
Making a mountain out of a mole hill
Here are mole hills. They show that some animals live underground.
Here is a mole. Moles are small mammals with dark velvety fur, a long muzzle, and very small eyes. They live underground. They eat insects only: they are insectivorous.
The idea here is that a mole is very small and a mole hill is very small too.
If you make a mountain out of a mole hill, you are considerably exaggerating what should be considered a small problem. You are over-reacting.
