I've been walking to class on all fours. it's an experiment in dourness and fourness. you see I've been searching for a way to act a little younger without it going to my head. you see I've been trying to find a way to appear youthful but not idiotic. I tell people that my doctor has required it of me. that my psychologist has said that it would be useful to humiliate myself at regular intervals throughout the day and this is the most effective way. I am my own psychologist.
