Hurray, it's Friday!

Unfortunately, as always seems to happen to me, a tooth started really, really bothering me after 5pm last night, just after my dentist closes up shop for the weekend... if I'm going to have a toothache why can't it be on Monday morning? And why is it that toothaches make me so grouchy? I've often had nightmares about losing my teeth, having them just crumble away, and heard this is one of the most common dreams, with all kinds of interpretations, but quite frankly, I think I just have those dreams because I'm afraid of losing my teeth!
