I WAS always taught in school by my English teacher that you referred to humans as ‘who’ and everything else as ‘that’.

Simple enough. But what about ghosts?

I ask because I was about to send off a page with a headline that read “We’re the ghosts that haunt hotels”.

So are ghosts human or not and how does this grammatical rule apply to them?

In the end I changed it to ‘who’ to respect the dead.

Ironically, the headline was for a column written by Colin Baker, pictured, the former Doctor Who actor.

I agree – ‘Doctor That’ just wouldn’t work, would it?
