I'm relaxed about that light approach and effort? (4,4,4,2)
I believe the answer is:
easy come easy go
'i'm relaxed about that light approach and effort?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'i'm relaxed about that light approach and effort?' is the wordplay.
I cannot quite understand how this works, but
'i'm' could be 'me' (both refer to the person speaking or writing) and 'me' is located in the answer.
'relaxed' could be 'easy' (associated in meaning) and 'easy' is located in the answer.
'about' could be 'c' (abbreviation for circa) and 'c' is found within the answer.
'light' could be 'easy' (similar in meaning) and 'easy' is found in the answer.
'effort?' could be 'go' (go is a kind of effort) and 'go' is located in the answer.
A single letter 'o' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for easy come easy go that I've seen before include "What cost no effort to get won't be missed" , "Like a rich spendthrift's salary" , "Nineteen sixty seven film with Elvis Presley" .)
