Living in vain

I'm living in vain
I'm just watching the rain
I wanna get out
But I just don't know how
I used to have a girlfriend
Who gave me a valentine
At first it made me nervous
But then I think it made me fine
Because I'm living in vain
I'm just watching the rain
I wanna get out
But I just don't know how
I used to have a grandma
She always called me "dear"
I never knew her purpose
I only knew her atmosphere
Because I'm living in vain
I'm just watchin the rain
I wanna get out
But I just don't know how
