Bring in the Violinist

So i have been in this certain sticky situation for the past 5 months. It involves a really close friend of mine and $300 dollars. I'm not one to name names, so for this certain post his name will be Bob. I lent Bob $300 dollars of my parents money about 5 months ago. When i put that $300 into his hand he said OK I will get this back to you. I agreed happily, believing he really would. Well, 5 months have now passed and I'm getting fed up, almost as much as my parents are. I mean it was not my money that I worked for, it was theirs that they worked hard for. It was extremely bad judgement on my part and I wish I could take everything back. My parents want to sue him, and at first I was scared because it might harm our friendship, but now I could care less about he feels. I mean he has had 5 months to pay it back and me nor my parents have even seen a penny. So I'm ready to file some legal papers and for him to bathe in the mess hes created among my family and among his stupid petty actions. This is another reason why guys are complete idiots. haha. My trust for them as a species just keeps going down the drain. haha. This is why I would like a violinist because it would fit perfectly when I hear him crying a river about all the money he is going to lose by this lawsuit.
