Cover art for What You Know lyrics by Two Door Cinema Club

It just dawned on me that this song might actually be implying a passage of time, which makes it make a lot more sense!

"In a few weeks I will get time To realize it's right before my eyes And I can take it if it's what I want to do"

Initial feelings about asking the girl out! He doubts himself, but he's plucking up the courage and he wants to do it. And then, "a few weeks" later rolls around...

"I am leaving This is starting to feel like It's right before my eyes And I can taste it It's my sweet beginning"

He's going to finally approach her, he's finally reached that point of courage, and he's hopeful and ready.

"And I can tell just what you want You don't want to be alone"

He understands, now, that this girl is horribly lonely and he wants to fill that gap in her life because he loves her, but he flakes out because he doesn't think he's capable of doing that for her.

"Maybe next year I'll have no time To think about the questions to address"

The next year rolls around, and he's aware that it's getting late in the game and she's still plagued with loneliness that's eating her up. He still entertains the idea of trying to be there for her ("Am I the one to try to stop the fire?")

"I wouldn't test you I'm not the best you could have attained Why try anything? I will get there Just remember I know"

Again, he gives up, because he thinks he's not good enough for her and that someone else would give her what she really needs. He thinks he should just not bother, but he stops himself, and convinces himself that maybe one day in the future he'll finally bring himself to try for real (again), and to remind her that out of everyone, he wants to her to know that he is aware and cares about her suffering ("Just remember I know...")

Also, from the way he sings, it doesn't seem resentful or bitter, but very sweet and sincere. Hence, why I believe he's a compassionate person who badly wants to help the person he cares about, but just doesn't have the balls/thinks he's good enough lmao.
