Question

the song the quiet things that no one ever knows by brand new.
can anyone explain the lyrics to me?

here are the lyrics:
We saw the western coast
I saw the hospital
Nursed the shoreline like a wound
Reports of lover's tryst
Were neither clear nor descript
We kept it safe and slow
The quiet things that no one ever knows

So keep the blood in your head
And keep your feet on the ground
Today's the day it gets tired
Today's the day we drop down
Gave up my body and bed
All for an empty hotel
Wasting words on lower cases and capitals

I contemplate the day we wed
Your friends are boring me to death
Your veil is ruined in the rain
By then you I can do without
There's nothing new to talk about
And though our kids are blessed
Their parents let them shoulder all the blame

So keep the blood in your head
And keep your feet on the ground
Today's the day it gets tired
Today's the day we drop down
Gave up my body and bed
All for an empty hotel
Wasting words on lower cases and capitals

I lie for only you
And I lie well...(2x's)
Hallelu...

So keep the blood in your head
And keep your feet on the ground
Today's the day it gets tired
Today's the day we drop down
Gave up my body and bed
All for an empty hotel
Wasting words on lower cases and capitals

Answer 1

The main character had an unreccomended sexual encounter at a beach hotel, and apparently it wasn't that good for him. Now he's deprived of sleep and it's hitting him hard as he deals with how to break off the marriage-minded woman he's with.
