<prompt> Human: Little bit of background: my cousin used to work as a chef in a vegetarianvegan restaurant in a 0.5M city. Besides that he helped with general development of the business. Since the restaurant is quite successful, the owner decided to grow the business in the form of a franchise. So my cousin, his brother and his girlfriend are building a new restaurant in a 1M city. They already got a loan from a bank but still would need more money. So he offered me to invest in their restaurant with return of 10 per year I would give them a loan. The loan would be backed up by a written contract. My cousin showed me some numbers and whole project looks promising.Is there anything I should be concerned, worried or cautious?  <response>: The only difference between you and me is that if things go south with me and I sue your cousin, Thanksgiving dinner isnt awkward at my house. Avoid.
