Quandary

A colleague has gone off to football practice in his lunch hour and has left what he is currently working on live on his screen. It’s some kind of presentation and features the word “assesment” (sic) displayed very prominently.

Oh dear.

Do I correct it? Do I leave a post-it on his screen? Do I drop him a polite email?

There’s nothing in Debrett’s about this, probably because the kind of people who read Debrett’s could not conceive of someone not being able to spell “assessment”.
