One Chance for Me, Please?

I know you can't see through it
But it's never really mattered to me
So exquisite and some kind of different
Your smile is so sweet

I'm not too sure of myself
Nothing more than a kid
Vulnerable, frightened, curious, alive;
Making mistakes all the time

Give me one chance
I want to show you who I am
And what I can be
Could you let me have that?

If I'm wrong, don't worry
I promise I'll disappear
