Helmet - Exactly What You Wanted lyrics

I'm not so good realizing Who i can or cannot trust It's best to keep what matters vague With harmless lies i can adjust I get a "d" for disappointment Now there's nothing to regret Everybody's good for something At least you know what you won't get I let you down again What's another harmless Lie between friends? Now you can be disappointed I thought i gave you just exactly What you wanted
