Is an author, you say, and behaves well (4,5)

'behaves well' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Perhaps there's a link between them I don't understand?

'is an author you say' is the wordplay.
'is an' becomes 'does' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'author' becomes 'write' (to author something is to write it).
'you say' indicates a 'sounds like' (homophone) clue.
'write' is a homophone of 'right'.
'does'+'right'='DOES RIGHT'

'and' acts as a link.

Can you help me to learn more?
