Melanie C - Understand Lyrics

I'm looking at the floor
I'm looking anywhere to try to put my head into a different place
I'm stopping it before, before I think about the promise to myself
That I'm about to break

Fall into daydreams inside these walls
I must be out of my mind

'Cause I don't even know you but all I do is think about your face
And I don't wanna call you but I wish I had your number just in case
And I never thought someone could shake me like you can
Some things weren't designed to understand

I hope you didn't see
I hope you didn't notice if you did I hope you looked away
I'll keep it all to me, I'll keep on running
'Cause it's only when I'm running that I feel safe
As I fall I must be out of my mind

'Cause I don't even know you but all I do is think about your face
And I don't wanna call you but I wish I had your number just in case
And I never thought someone could shake me like you can
Some things weren't designed to understand

TV shows and cars that won't slow down
I should be looking for a chance but don't know how
Disillusion never let me down
Don't lose it now, don't lose it

I don't even know you but all I do is think about your face
And I don't wanna call you but I wish I had your number just in case
And I never thought someone could shake me like you can
Some things weren't designed to understand
Some things I will never understand
