i sold my friend some parts for $200 that would have cost him $600 anywhere else. well a couple weeks later , a different part breaks on my truck and this freind has a this part and will give it to me for the $200 he owes me. i say ok. i spend 8 hours and intstall this part and all is well. then two weeks and 600 miles later , this part breaks internally and i am back to square one. of course he thought this part was good, and didnt think this would happen. if you were this friend , what would you do? 1. give me my $200 that you originally owed me forstuff i gave you? 2. give me half my money originally owed ? 3. or would you tell me sorry and go about your day ?
