Lots of these getting solved; I'm gonna have to write some more soon...

Those who have me won’t point it out;

Those who don’t, they jump, scream, and shout.

I cover up the truth so no one will see,

But there is nothing wrong with me.

I’m always polite but often misplaced,

And when I am false I’m always in bad taste.

Am I hard to guess? Please, don’t make me red…

I’m sure that the answer’s right there in your head.

You’re ever so brilliant, and I’m dreadfully slow.

If you think about it, my name you will know.
