As a rule, I keep the secret, when I am asked from anybody.

It ranges from elders and youngers to relatives, except for illegality or emergency cases.

However, I also ask them not to keep the secret over two years, as a condition.

If they want to extend the period of "two years", I will ask them to update the condition within the period.

I think that "the period of two years" is enough for them, if they don't have an intention to update the condition.

Incidentally, there has been no person to try updating since now.

In addition, I will say to them,

"After two years, I will disclose everything including" Who told me? "

So, they come to get nervous, and stop talking anymore.

Of course, a chill comes over the company.
