I will tell you
I’ll tell you what I did today.
Les contaré tales historias, que ellos mismos se volverán locos.
I'll tell them such stories that they'll go crazy.
— Moscú no cree en las lágrimas (1980)
I'll tell you everything.
Ahora les contaré una pequeña historia.
Now I'll tell you a little story.
I'll tell you a story.
