I from this day forward am not going to lend any more to anyone because I never ever get it all back and I just can't afford not too.
Lending money to people in good faith thinking you will get it back and then not getting it back can lead to really stressful times. Like if one of the people I had lent money to hadn't paid me back today I would have been able to pay all of my bills but wouldn't have had any money left until my next pay day next week and that would have made for a rubbish week!
Moral of the story is, if you don't think that they will pay you back --- dont lend it to them!
