Jury Duty

So I am sitting here this morning going through the pile of mail that I have neglected since getting back from vacation. As I am sorting I come across an envelope marked... JURY DUTY. I say to myslef, "Crap- I missed it." I forgot that I had called to postpone since I was going on vacation only to come back from vacation to forget I was supposed to go there... YESTERDAY. Now what do I do? Call and say, "Uh, sorry but I forgot?" Is there a fine? Am I in trouble? Should I even call to find out? Is it one of those things that if I never say anything no one will even notice? Or is it worse if I don't call to say I am a dumbass? I don't know what to do.
