Dear Lucy, Your recent payment of one incisor was credited to your account yesterday. Be aware that due to shifts in certain volatile market assets you are currently in a position of significant negative equity vis-a-vis your dental assemblage. I have regretfully decided to foreclose on your remaining debt and would appreciate your payment of the outstanding balance (currently assessed at two canines, a premolar, two molars and a wisdom tooth) by close of business Thursday.
Dear William, It has come to my attention that your brother George has never provided me with a tooth in trade. I would muchly like to add one of his pristine enamels to my collection, but based on his unwillingness to cooperate, I beseech you to acquire one for me. I will pay triple the going rate. It would please me to no ends if you would procure for me the complete collection, at which time I may have another little favor to ask. Yours In Good Faith,
