The forgetfulness story of inventor Edison

The following little thing is enough to prove this problem.

Once, Edison went to the tax authorities to pay taxes. At that time, he was absorbed in studying a major scientific problem. There are many taxpayers, and the queue is like a long snake, and they go to the counter to pay in turn. When it was his turn, he couldn't even say his name! He thought for a long time, but he still couldn't remember his name. Finally, it was his neighbor who told him that he knew his name was Thomas Edison.

The joke spread like wildfire, and many people still remember it.
