Disappointment when everyone keeps their emotions in check? (3-5)
I believe the answer is:
non-event
'everyone keeps their emotions in check?' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'disappointment when' is the wordplay.
I cannot quite understand how this works, but
'when' could be 'on' (I've seen this in other clues) and 'on' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for non-event that I've seen is " disappointing affair".)
