five years...lol wtf? 
Long story, yes. But I will spare you the bullshit involved.
Gave her a loan of 3k for some medical issues, she paid back within 2 weeks.
Then she came to me and was up front about the next loan, saying that she'd be unable to pay it back as quickly. I gave her the $, she paid back a couple hundred, and then dropped off the radar, though when I engaged her we'd talk and keep in touch. Finally after some time, 4yrs I guess, I asked her straight out "Are you screwing me or just taking an extra long time to pay me back? Just want to know if I'll ever see another cent."
She began payments again, and once her and I had a falling out over something else, she paid me off one lump some. Too bad I never got the interest on the money SHE APPROACHED me with. But the original loan was paid off, so at least that happened.
