Everyone out there is pretty familiar with Gandhiji's three monkeys i.e.
see no evil, hear no evil, speak no evil!
Well, this is slightly different version of same essential in present era from these little versions of ours point of view, they are trying to say
Don't show us evil, don't make us listen to evil, don't put us in a position to talk bout evil!!
Because we imitate, because we inherit!!
