I realize 2 things
1) I have $1100 that i got from John
2) I am still missing $900 from my original $900 that i will probably never collect from Peter.
Here is my solution
1) I go to John and tell him that he's now responsible for the other $900, or ELSE!
2) I take $1100 that i got from John and spend it for a "job creation event in my neighborhood" and by that i mean going to a strip club of course.
