The reason is simple: they always return the money to me late. And I absolutely hate that.
Hopefully, I'll remember my plan which is as follows...
[[ I'll expect the money back within 2 days. After that, I'll begin to charge 10% extra per day. If I don't get the money back within the first week, the interest rate will increase to 15% the second week, 20% the third week, etc. (A 5% increase per week.) ]]It's not that I don't trust my friends; it's the fact that I either get the money back a month or two later ('cus by that time, I begin to hunt the person down) or I just don't get it back at all (which results in me disliking him/her, having no trust in him/her, and never letting him/her borrow anything else ever again).
