hard, tough
Times are tough.
Metals are very hard.
Creo que fueron demasiado duros con él.
I think they were too hard on him.
— La vida de los otros (2006)
Because times are tough.
Casi siempre son tipos duros; muy pocas veces las chicas.
They're almost always tough guys; very rarely are they girls.
