Belle and Sebastian - Young and Stupid lyrics

I was yelling in my sleep
I was crying feeling week
Do we have to feel this way
It wasn't like this yesterday

Everything is fine
When you're young and stupid
Everything's divine
When you're young and stupid

There's an easy start to things
There's the thrill that beauty brings
Glued together at the hips
Stuck together at the lips

Nature has the lead
When you're young and stupid
Nurture will impede
When you're young and stupid

Now we're old with creaking bones
Some with partners some alone
Some with kids and some with dogs
Getting through the nightly slog

Flashes in the mind
You were young and stupid
Keeps us warm at night
All our young and stupid

Makes us feel delight
We were young and stupid
Makes you feel regret
When you're young and stupid

You know I kept remind
Myself that nothing matters
Nothing matters
You know sometimes you have
A fight with someone
Or you get frustrated or
You know something
Happening and you catch
A little glimpse of the outside
And I don't know
It's just a bird flying or you see
A funny shape in the cloud
And you think what am I doing
You know, I'm so small
Nothing- nothing matters
So whatever
