So, what are you up to, you frozen whale, you smoked, dried, canned piece of soul, or whatever else I would like to hurl at your head filled as I am with 70% anger and 30% pity. You have only the latter 30% to thank for my not having sent you a can full of minced onions and garlic after you so cravenly did not show up on Easter. But why have you still not sent me your dissertation? Don’t you know that I am one of the 1 1/2 fellows who would read it with interest and pleasure, you wretched man?
