Having to pee. No shame, it happens to some mothers after they have kids. I had a weak bladder problem as a child too, but I had it under control until I had my kids. There's an example for you. (Just so you know, I do make it to the bathroom before it goes down my leg, it just hurt to hold it!)
It is 1:23 PM right now. I am writing a final paper that was due at 9 AM. 9 AM yesterday... It is the most stupid paper I have written all semester and I very much dislike the way in which the teacher tries to promote learning.
