It's all Latin to me

I have this little sister Kirsty, she is small and very funny. Often we trade words or phrases we have found, or grammatical errors in official documents. This morning we dabbled in a little Latin, as I'm sure many of you do from time to time.

Hers: 'Functus officio' - roughly means 'my work here is done'

Mine: 'Sic transit gloria mundi' - is kind of like 'all worldly things are fleeting' or 'thus passes the glory of the world'

Yes, we are nerds. We both agree that being a librarian is one of our dream jobs, and cannot abide poor spelling.
