I love my mother so much, and she raised me and my brother really well!
She used a method a little 'iron, let’s say that she never slapped or kicked us, but did a simple countdown of 3 seconds with a look that was the "Terror in person" and with a calm but threatening tone, so even more frightening, which increased with ever second that pass...
In fact, it never happened that my mother exceeded 2 seconds, so imagine it! XD
