When I was a new graduate, I attended to the reception for new alumni. The representative of the alumni said as follows,
''Welcome to join the alumni community. today I will share a wisdom.
Respect for ladies and old persons.
Because you are young men, so you can not understand a nature of ladies nor old persons.
You became scientists. Scientists must respect for the things they have not understood, and they must treat them carefully with the mind of modesty.
That is why I request to you to respect for ladies and old men.''
