Sorprenderse, entristecerse
Is there any grammatical reason why one uses "de que" and one uses "que" here, or does it just depend on the verb? These are from a homework packet.
Se sorprenden de que yo haya entregado los papeles ayer.
Se entristece que su novia se haya olvidado de la fecha de su cumpleaños.
