what he/she told me
Debería haber hecho lo que me dijo la médica.
I should have done what the doctor told me.
A pesar de todo lo que me dijo, no puedo parar de pensar en ella.
Despite everything she told me, I can't stop thinking about her.
No te puedo decir lo que me dijo Tom.
I can't tell you what Tom told me.
I didn't understand what he told me.
Guess what he told me.
¡No vas a creer lo que me dijo Tom!
You won't believe what Tom told me!
So I did what he told me.
