So, let's say you've got 3 family members who are running a small business together. Due to a problem they claim is of a temporary basis they need € 25.000,-- ($ 40.000,--) which they say they will pay back by the end of this year. For reasons you don't know they haven't been able yet to borrow money from another source. You have the money, but you also have other plans with it roughly at the time it would be paid back if all goes well.
Would you lend them the money? And if yes under which conditions?
