He was riding motorcycle
Sometimes people cannot notice anything surrounding them when they are happy. But, particular scene in a drama I watched came to my mind once I saw someone making a phone call while riding motorcycle. I was walking home after bought a new pair of shoes.
In the drama, originally from Korea, a policeman stopped a car driven by a woman who is having a phone-call without using wireless earphone. Punishment point was given and she was told not to do it again otherwise she will go to jail and sleep there for few days.
Just like people advertising save-drive through TV, advising people to stop their vehicle if they feel sleepy. Since it is very dangerous driving in that condition, it is better continue driving after taking a rest or sleep for a while, It should apply to they who want to make a phone-call, too.
The guy who was making phonecall was riding a motorcycle in a big city, where cars, trucks pass those crowded streets regardless of time. This may happens to other cities in the world. The guy, nothing happen to him till he disappeared from my sight. But who knows, in other part the world someone died because they did something that they should not do while riding motorcycle or driving car. If you die because of your ignorance, wouldn’t that be too many regrets?
