I always appreciate an effort to repay but what I really want for repayment is their effort in helping others the next time they have a chance to help.
I dont need to be paid back, I want more folks helping. It selfish, know; I may need help later on and I want more folks helping to increase my chance of getting help if/when I need it.
I think of it as starting a network of helpers instead of just a single completed transaction.
