So many of Taylor Swift’s songs are about her life, but not all of them are.
She told the outlet, " …
I came across this picture of these two kids dancing at a dance.

It immediately made me think of how much fun they must have had that night."
Swift said she realized the teenagers were Ethel and Robert.
“She’s very kind and … do you know what she really is?

She had never sailed before.
She had never gone dragging before, she dragged.
She played everything that everyone else was doing and she was good at it” (viaVanity Fair).

That implies that “Everything Has Changed” is about Swift’s blossoming relationship with Conor Kennedy.
However, their relationship eventually fizzled out.
The “Begin Again”-Conor connection can be interpreted in two ways.
The other theory is that it is about Swift moving on from Conor and onto a new love.
“Starlight” has not been forgotten about since its 2021 rerelease.
