Stop it

I can see in your eyes,
That you view only flaws.
Plotting my demise,
Shredding me with your claws.

You never know everything,
You conceive it all on the spot.
You tell them anything,
It all adds to your fearsome plot.

I have to cover all in whit,
One flaw can determine it all.
If you see it, you'll expose it,
Pick it 'til it creates my fall.

Of all I'm ashamed you enhance,
It makes you laugh and smile.
But it also gives me no chance,
So maybe you can stop it for awhile.
