Murmuring is saying something in a low or indistinct voice or it also means to #express one's discontent about ( #someone or #something) in a subdued manner. Complain, moan, mutter and grumble are synonyms of murmuring.
I have one way or the other murmured or complained to myself when asked to do something that I feel its a disturbance to me but cant say no. I have also realised that, once you murmur you cease a blessing
#Murmuring is not a positive attitude...try to avoid it anywhere you find yourself. You get blessed only when you do what you do from your heart and this makes everything beautiful at the end if it all rather than working hard admist murmuring. That wil be a COS 90 job done or equal to 0.
