I bet he's lived his life so far as
the big fish in a very small pond.
أنا متأكّد أنّه عاش كمعلّم على نِطاق ضيّق جدّاً حتّى اللّحظة
Er war bisher sicher immer
der große Fisch im kleinen Teich.
Debió pasar su vida como el pez gordo
de un estanque pequeño.
Ha pasado su vida como el pez gordo
de un estanque pequeño.
Il a toujours dû vivre
comme le roi de sa petite jungle.
Di sicuro finora ha sempre vissuto 
come il signorotto del suo piccolo regno.
Provável que tenha vivido como
 o rei da cocada preta até agora.
Видать, он всю жизнь жил как единственная
крупная рыба в маленьком пруду.
