That's a new aphorism for me.

I like that.

Sad, but true. Very wise.

Thanks.

Thanks.

English is not my first language. but why is there an A before last word in a last row?

Alesko, it's a mistake. English must not be the creator's first language either.

Thanks.

The phrase works both with and without the A in the last row. If the last word is a noun then the A is necessary. If the last word is a verb then the A is not necessary. By including the A the phrase relates to a particular instance, a particular matter requiring action. Without the A the phrase would be more general.

Thank you.
