Next Sunday we’re going to have a look at characterisation and character. 
As Tony rightly said, ‘characterisation’ is all the stuff about your character’s favourite colour and the books he likes to read. ‘Character’ is about what he does in a crisis. 
There are loads of questionnaires online to help you with characterisation. I have chosen this one because it doesn’t expect you to work through a huge list. Instead you choose the most important ones. 
Do that for a character, and then write a short scene in which the character shows how he/she reacts in practice. 
Here’s the link: https://thejohnfox.com/2016/06/character-questionnaire/
Hope to see some of you on Sunday.
