If I was ...stuck on an island with plenty of food, a companion, and a relatively stress-free lifestyle...
I'll tell them: Not now buddy, let me have some peace...!
I would say this would be my obvious choice!
Stress free is the thing I want to be. I would tell them...."Buddy give me some time..if I have any problems i will see through them for a year... and then you can come to pick me up... else....T-T-M-M!"
