Si no te quemo debo quemar a cualquier otro.
If I don't burn you, I have to burn someone else.

Si no te comiste el pastel que hice, entonces lo hizo tu hermana.
If you didn't eat the cake I made, then your sister did.

If you don't know the answers, guess.
Si no te has comido tu plato en tres minutos, no recibirás postre.
If you haven’t finished your meal in three minutes, you won’t get dessert.

If you're not interested in them, why did you record them?
— La dolce vita (1960)
No es verdad, si no te importara nada, no te importaría decírmelo.
