# Society lubricants

By Murray Bourne, 14 Oct 2005

On my mathematics website, Interactive Mathematics, I have a "Comments or Questions?" feature on every page.

Some of the questions are, well, difficult to answer:

how to work out mathematics?

Others are much clearer:

What is the degree of differential equation?

Is differential equation has unique degree or not?

But most, like the one above, are totally devoid of "please". This is a free service, after all.

Some questions take quite a while to answer. It is very rare to get a thank you in reply. Lately I have been adding the following to my answer mails. Is it too cryptic, do you think?

"Manners are the lubricant of society..."
