Dear Kendroth,

What?! That poni you confronted was a poni by the name of St. John Allerdyce. He is a nasty poni who have been giving my students and I a hard time for years! Ithought he was in jail but I thought wrong. I am sorry for my ignorance and should have known. 

Did you really have a speak prepared?  How long was he out and how long did it take you to make and memorize it? Most likely not long, but still, an hour or two is still something that could have been used for much else. I am still glad you were able to deal with him but still sorry you had to.

The Business Poni you got that IOU from is a poni by the name of Filthy Rich. He is one of the biggest and best known in our town. The reason you don't know him is because you have been with me until recent and I have yet to do business with him. I don't know what you can use that IOU for but it can be handy in the future.  IOUs are used to signify someone wanting to pay you back for something kind you did. It isn't rare but isn't extremely common either. Just don't be surprized when someone give you one and don't expect it from everyone.

I hope that helps, please write back soon.
