How i discovered my debt

It was 12:30 in the night and i was half asleep. As i pulled the blanket over myself, i spotted a bed bug crouching in the wool, its heart leaping at the prospect of tasting my blood. I decided he had had his share of sin on the planet and looked around for a piece of paper. I found nothing save an envelope. Curiously, i'd opened the envelope but i'd not checked the contents. It was from ASU. I pulled out a sheet. It had something about paying bills online. Impatiently, i turned to the rear side of it. There was print there too. I was disappointed. I wanted to see the borrowed blood, my blood, smeared clearly against the paper's white. So i pulled out another and looked straight at the rear. It was white as snow and i smiled with satisfaction. Then i quietly used it to finish my good deed for the day. Just then, some strange impulse made me turn to the other side, and i saw that it was an unpaid bill for 220 dollars! Then i checked the due date, and it said 25th of May, the Friday that just passed. Now i have to pay it up with a late fee this coming week. Still i can't help but smile at the most curious way in which i stumbled upon this bill. Otherwise, its most likely i'd have trashed the whole envelope without a glance, and wouldn't have realised until the next bill came along, some four months from now, well into my fall semester, with a fine as severe as the due amount itself! I expect the bug was sent to heaven after all.
