 سرقت

یکشنبه بیست و هشتم مهر 1387

There once was a man who went to a computer trade show. Each day as he entered the man told the guard at the door: "I am a great thief, renowned for my feats of shoplifting. Be forewarned, for this trade show shall not escape unplundered."

This speech disturbed the guard greatly, because there were millions of
dollars of computer equipment inside, so he watched the man carefully. But the man merely wandered from booth to booth, asking questions and
humming quietly to himself.

When the man left, the guard took him aside and searched his clothes, but nothing was to be found. On the next day of the trade show, the man
returned and chided the guard saying: "I escaped with a vast booty
yesterday, but today will be even better." So the guard watched him ever
more closely, but to no avail.

On the final day of the trade show, the guard could restrain his curiosity no longer. "Sir Thief", he said, "I am so perplexed, I cannot live in peace.

Please enlighten me. What is it that you are stealing?"
The man smiled. "I am stealing patterns", he said.

جمعه نوزدهم مهر 1387

دوران کودکی‌مان و نانوايي به شكلي به هم گره خورده‌اند. صفهاي طولاني نانوايي، عدم رعابت نوبت توسط بزرگترها و تلف شدن عمر گرانبار. اين موضوع آن قدر شايع بود كه براي آموزش رعايت حقوق ديگران، از داستان نانوايي در كتاب فارسي استفاده مي‌كردند. 
يكي از دوستان عكسهايي از يكي از نانوايي‌هايي قم فرستاده بودند كه خيلي برايم جالب بود. جالب‌تر آن كه به شكلي با حرفه‌ي ما مرتبط است. ببينيد.
