If there is a closed door, knock, it might open. Or it might not. But you will never know till you knock.
And if you knock, and there is no answer – maybe you need to knock harder. If you knock again, and it still remains closed – maybe there is nobody there. If you knock a third time and there is still no movement – surely, nothing is there. Or maybe they don’t want to open. So stop disturbing.
It all depends on how you feel on the inside.
Wearing bright clothes is not enough. One has to be bright and happy on the inside too.
