After your surgery, you tell me that you can't mow your own lawn anymore. After finishing cutting my lawn, I also cut your lawn which is very overgrown. We have . a. a quasi contract in which the law deems us to have agreed to avoid you receiving a benefit at my expense. b. no contract. I performed a gift by mowing your lawn. c. a contract, but only if you agree to pay me. I am not any legal obligation to do so.
