GAH - forgot my library books were due last week

I hate stress. Realized a little while ago that I have library books that were due back on the 10th. Ouch! Six books at I think it's thirty cents a day now. ::whimper:: Dang stressing out the past week I forgot I even had them out, much less that they were due back in. I never did get to finish reading the James A. Michener or Janet Evanovich ones either. Will need to get them again.
