Al perro que duerme, ¡¡¡no lo despiertes!!!

 …LET SLEEPING DOGS LIE…

If someone is told to let sleeping dogs lie, it means that they shouldn’t disturb a situation as it would result in trouble or complications.

Refrain from disturbing people or from debating topics not currently causing one any trouble.

Example: It may be that he used to live with Miss Bloggs; but I don’t think you ought to refer to that topic in front of his wife – it’s better to let sleeping dogs of that sort lie.

A fleeing enemy, silver bridge ( A enemigo que huye puente de plata)
Who grasps at too much loses everything
Appetite comes with eating
“Be more apañao’ that a peseta”
