Cover art for Last to Know lyrics by Three Days Grace

This song is not about relationships with an opposite gender. This is actually about a drug addiction.

The whole switch a roo, to him being broken hearted to him being okay is all about him going from addiction to being a okay after getting over the addiction. He refers the drug as a she.

As the end says.

"and when she leaves you for dead, You'll be the last to know"

It's the drug taking advantage of the next person's addiction. Taking him/her all the way to death, and him not being able to know about "she" left him for dead. As the drug killed him/her.

Um, yeah. This song was Adam singing to coke wondering why a drug didn't tell him what the hell was going on.

Makes sense.

Wrong, it's about a first love he had with a women and how she cheated on him...it's in an interview while they were making the Life Starts Now album.
