Name Withheld, Manila, Philippines
YOU SHOULD endure your loss with stoicism. It's admirable that you were willing to help a friend and unfortunate that you were robbed, but it doesn't follow that your friend pay back any of the stolen money. You never actually gave your friend any moneyeven if it was because of your bad luckso there's nothing for him to repay.
If you trace any chain of events back far enough, it's all somebody else's fault. But it's not fair to think this way. Why not send the bill to your penniless friend's parents? If they had never met, fallen in love, and gotten married, he wouldn't have been born, descended into hard times, and needed a loan. Or his grandparents, or...well, I think you see where this is going.
If the robbery left you too broke to lend any money to your friend, so be it. But then everybody loses. Except the mugger.
You might take some comfort in the old maxim "No good deed goes unpunished."
