This note was found inside a high school textbook that I bought at this great used bookstore in San Francisco (I think I've since heard that it closed, but it was on Church Street right by where you got off the J train in Noe Valley). It's not as crazy as some of the other found notes I've put up this week, but I like it anyway. The author, who is clearly Robert Arias, never handed it in... did he type up a cleaner version or come up with a less lame excuse? Or did he just keep this on hand inside his General Mathematics book in case he ever needed an excused absence on short notice? Also suitable for speculation: is this Rinken fellow French?
