One day, I was in need of something, but too shy to ask and was afraid maybe they won't give it to me, someone else then asked for it, they refused, but the guy did not give up, he kept on asking, to my greatest surprise he got it.

It's the same way, sometimes it might seem your cries are not heard.
Maybe it isn't loud enough,
Shout if you have to, keep knocking that door must answer you.
Thanks
