I do not remember "When I was on dating, I had a problem with topics".

It might just be "no memory", and moreover, the number of dates of mine, might be also very small. It happened to have been so.

Even now, my wife said,

"Why can you talk so much in the middle of the night, after you worked harder and tired in your company?"

Even if she says "Why", I do not understand well either.

The reason might be, I work quietly at my office. or laboratory alone all day.

I am quite talkative, so I know I should not criticize other's talks;

Nevertheless, as an engineer of information systems, I come to get angry with conversations that do not utilize the communication resources.

------

There was a young lady speaking by smart-phone in a conversation mode, in a Yokohama municipal subway train.

The voice of a man, heard from a smart-phone probably was her lover.

Male: "Hey, where are you now?"

Female: "Where do you think it is?"

Male: "Yeah, I do not know at all. Where are you? "

Female: "Where am I (with smiling)?"

------

Taking up the lady's smart-phone,

"It is a point about 20 seconds remaining until the municipal subway Shonan-dai. She will get off soon!"

I wanted to shout out loudly to the smart-phone (just I thought)

"Do not crush precious communication resources (frequency channel, communication band) with conversation with zero information!"

I thought that.

I know well that

I was wrong.
