Okayyy fiona, you never know if it has anything to do with “little lamb dragonfly” 👀
Do you mean the song Never Know?
There's a connection via the line "Since you've gone I never know / I go on but I miss you so"
I actually am pretty partial to reading Little Lamb Dragonfly as about John, and I see how they depict similar emotions, with Never Know feeling like it's the lead-up to the break and Little Lamb Dragonfly dealing with the aftermath ("Don't know why you hang around my door / I don't live here anymore").
"Dragonfly, the years ahead will show / How little we really know" <- there's something tragic about this line in this context. Personally, I'm not convinced there's a lot more clarity on what exactly caused John and Paul's fallout today, it's more that Paul has found a way towards acceptance. "I love you but I never know" could thus be read in a Here Today sense ("Never understood a word / But you were always there with a smile"). That song is specifically about coming to accept that you may never fully know someone but that doesn't erase your love for them.
