I hope the fishes keep you warm tonight

When I first stepped in,
I couldn't see it

The second time I walked in,
I still couldn't find it

The third time I went,
I knew it wasn't there since the beginning

The next time I got there,
I brought it with me and left it

And the following visits,
I could see it everytime

On my stay,
I use it anytime

Today I couldn't be there,
But I hope the fishes keep you warm tonight

Because when you're not around,
It is the fishes that keep painful shivering nights away from me
