How Can I Be Sure

How can I be sure in a world that's constantly changing?
How can I be sure where I stand with you?

Whenever I, whenever I am away from you
I wanna die 'cause you know I wanna stay with you
How do I know? Maybe you're trying to use me
Flying too high can confuse me. Touch me but don't take me down

Whenever I, whenever I am away from you
My alibi is telling people I don't care for you
Maybe I'm just hanging around with my head up upside down
It's a pity, I can't seem to find someone who's as pretty and lovely as you

How can I be sure? I really really really wanna know
I really really really wanna know
How can I be sure in a world that's constantly changing?
How can I be sure? I'll be sure with you
