I'm a teacher, watching my students take an exam. But all is not well - I have the beginnings of terrible stomach cramps, and whatever I do (crouching, stretching, sitting, standing) the pain just increases minute by minute. I make it through the last 15 minutes of work, but once I get home, I strip off my blouse, stockings and high heels and abandon myself to the pain. Lying on the bed, shifting position to try to make myself more comfortable, my abdomen contracts and the soles of my feet scrunch as I try to manage the pain...
