Predator Mode

School ended normally, even though it was the last day of official school term. Dr Chan let us off early, seeing as we need to mug for physics practical tomorrow. I decided to go home to rest, since it was not worth the wait for my senior to arrive. Told her that I was sorry and was too tired to meet her. Meanwhile, I must be prepared for the Hunt tomorrow, equiping myself with the latest equipment. Must go and check the conditions of my french curves and find available test tubes.
