What does "seal" mean in the lyrics below?
When will I see you again?
You left with no goodbye, not a single word was said
No final kiss to seal any sins
I had no idea of the state we were in.

What does "seal" mean in the lyrics below?
When will I see you again?
You left with no goodbye, not a single word was said
No final kiss to seal any sins
I had no idea of the state we were in.

Answer

In this case "seal" means "close the door", and "sins" refers to the bad things she did that caused him to leave. It is a metaphor, she is saying she wants to put her sins in a box and close the box so she can forget about the relationship. But because the sins were not sealed away, she is still thinking about them.
