Sure Know Something

The speaker describes a powerful past relationship that still affects him. He has been lonely, confused, and hurt, yet at night he continues to miss and desire the other person. The repeated chorus expresses confidence in what he has learned from this experience, even though his feelings remain unresolved.

“Up and down” suggests passing through changing fortunes or emotions, while “hypnotized” and “paralyzed” convey how strongly the relationship seemed to control him. Saying the other person showed him things “they never told me at school” likely means he learned about love, desire, or adult feelings through experience rather than formal lessons. “Nobody’s fool” means he believes he is not easily tricked, despite admitting he has taken risks.

The song holds two ideas together: the speaker sees himself as wiser now, but he is still emotionally attached and remembers the pain. His claim that he “sure know[s] something” may refer to hard-won knowledge about love, or simply to how certain he is of the bond’s effect on him. The lyrics do not explain whether the relationship could return; they focus on lingering feeling rather than a clear resolution.
