LET THE CAT OUT THE BAG

IF YOU ARE TALKING ABOUT SECRETS AND YOU CAN'T HOLD YOUR TONGUE, PROBABLY YOU WILL LET THE CAT OUT THE BAG. WHEN THE SECRET IS SPOTTED, THE CAT WILL BE OUT THE BAG. IN SPANISH WE HAVE: SE HA DESCUBIERTO EL PASTEL. AND THAT MEANS: IRSE DE LA LENGUA. SO BE CAREFUL AND IF YOU KNOW A SECRET DON'T LET THE CAT OUT THE BAG.
