Dr. Prudence looked on as Maria performed her experiment.  Maria was nervous as this was her final examination.  Dr. Prudence had never liked Maria and was watching her like a hawk.  One mistake and she would fail Maria.  Maria's palms grew sweaty as she squeezed some fluid from the pipet.  Careful she thought to herself, too much can ruin the experiment.  Maria watched as the liquid reacted changing to a dark green, then a purple.  Maria squeezed her eyes shut as she hoped she had put in just enough to keep it at purple.  She winced as she heard Dr. Prudence clear her throat.  Dr. Prudence said, "Well done Maria, I guess I underestimated you."  Maria smiled as she could finally relax and enjoy the fruits of her hard work.
