Lyric discussion by ryantoyota 

I think one of the key clue in this song is in the line "an unfortunate slight." It confused me at first because it was seemingly just pieces of a sentence, so you start wondering "slight of hand," "slight of plans," someone else mentioned it could refer to slight differences between characters, but none of that really made sense to me. I decided to look up "slight" in the dictionary, and guess what? It can be used as a noun (as it is in this case). Here's the definition: "an insult caused by a failure to show someone proper respect or attention." So it sounds like either she did something to disrespect him, or the other way around and someone let an insult slip that they regretted.

Personally, I see the song as romantic interest that's crossed the line and she's now saying she wants to take it slow. She's intrigued by the idea that he likes her, so invites him over, but then things get frisky, someone is disrespected, someone gets angry, and then it changes to "okay, stop right there, I'm kicking you out." Not that it's over, but she just needs time to think about it and take things slower.

An error occured.
