Unbreakable

The code had to be delivered before the clients came in the next morning.It refused to work properly and behaved much like an extremely difficult co-worker. It decided to work perfectly till 1800 HRS and then suddenly threw a fit. She looked around to realize it was long since the place was deserted.

In panic she called him on the other side of the globe. She knew he'd be asleep but he was her last chance to dodge the blame.
He picked up the call almost instantly, heard the issue and logged on to the system.

She couldn't believe that she could have missed this. She should have checked the basics before escalating the matter.She should have been more conscious of the code.
She feared the worst as he was about to say his next few words.

He said 'That's nothing. I make worse mistakes even with so many years behind me. The trick is to learn from everything'.
And she learnt magnanimity.
