A Dog's Tail is Never Straight
ديل الكلب عمره ما ينعدل
A dog’s tail is never straight.[1]
The lazy and incorrigible are never cured of their bad habits.
In what can fairly be described as a well-deserved insult, an exasperated tutor from Luxor taught me this expression. It was among the only things I learned from him.
“Never,” it turns out, is relative, as seen in more colorful Syrian variants:
ذيل الكلب أعوج لو وضعوه في القالب 40 سنة
A dog’s tail is crooked even if it were put in a cast for 40 years.
ذنب الكلب بضل اعوج لو انحط في القالب مليون سنة
A dog’s tail stays crooked even if were set in a cast for a million years.
