Can't stay put

I heard about a four foot shark in a five foot tank
And it makes me wonder, it makes me think
That if I had fins, and your arms were the glass
That sooner or later, I would start to feel trapped
Don't take it personally, I was born with restless feet
And I just can't stay put

When things are good, I get so scared
So when they fall apart, I'm well prepared
And i'll tell you right now that it won't be love
But a little time well spent is better than none
And I'm always to blame for snuffing out the candle's flame
But I just can't stay put

And it may not be fair for me to string you along
But here are your scissors, you can do what you want
And there's not much more that I could say
But I like to be honest with the games I play
And If I grow old, and I end up dying all alone
It's cause I couldn't stay, no I just can't stay
I just can't stay put
