Don't delay rushed, curt thank-you note? (2,4,4,3,7)
I believe the answer is:
no time like the present
'don't delay rushed curt thank-you' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'note?' is the wordplay.
I cannot quite understand how this works, but
'note?' could be 'ti' (musical note, as in do re mi so fa la ti do) and 'ti' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for no time like the present that I've seen is " This is a very suitable moment (2,4,4,3,7)".)
