Why would you threaten someone with bodily harm about an advert promising to go back in time? People are weird

But many letters came from people who wanted me to correct a past tragedy. Dozens, in prison, asked me to go back in time and talk them out of committing the crime that put them away. Others (and not a few) were from people who begged me to go back and save a loved one from a tragic death. Those letters were so heartbreaking I almost couldn’t read them and I felt a certain amount of shame for not anticipating the false hope I placed in so many hearts.

On the other hand, I also got letters from people who, despite postal regulations, threatened me with either bodily harm or death if the ad turned out to be a joke or a scam. I guess it all balances out.
