Unless you know the person very well, and it's an absolute emergency, I wouldn't recommend borrowing or lending money. That's a sure way for friends to become fast enemies, and it would be a sad shame to lose a friend over money.

Well borrowing money and not repaying it is a great way to alienate people!

Borrowing money is one quick way to alienate people! Even your family and friends, wait, especially your family and friends!You might just as easily douse them in gasoline and toss a match at them.It's a poor way to win friends or influence people.
