Lending money or any other valuable goods to family & friends can cost you both the money and your friends if proper agreements/contracts did not take place. Over years i lost around $2500 cash to 3 people and an organ worth $500 that was borrowed by a friend and never got it back. I also lost valuable books, Cds and other stuff because people are just careless and selfish so hard lesson learned but never never again. Seriously people, if someone lent you money or an item , the least you can do is appreciate and return it on time without causing embarrassment and tensions. How common is it? Did you lend anything to someone and never got it back or are you guilty of one? Honest answers please.
