neglectfulness

I'm a little stuck... Click here to teach me more about this clue!

'lack of care and attention' is the definition.
I can't judge whether this defines the answer.

'glenn's left cues about' is the wordplay.
'about' indicates an anagram.
'glenns'+'left'+'cues'='glennsleftcues'
'glennsleftcues' anagrammed gives 'NEGLECTFULNESS'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
