When I was younger, I had a cell phone. My republican uncle and his wife be trying to mind fawk me by asking me them question like why do I need a cell phone. To them, a cell phone is exclusively for those who are in business related fields. I told them that I'm a traveler and I may need it for emergency use and yes, It has bailed me out of tough situations at countless of times before.
They thought I was a loony until it happened to them.
Another uncle, I once said this line when I was just a kid. I said..."I'm afraid to be fat" . He laughed at me and said boy you are stupid. Now his azz is fighting for his life with fat related illness like high blood pressure / cholesterol and other sicknesses issues.
The moral of the story is this. Sometimes, something simplistic, you just have to give people the benefit of the doubt because they could be living way beyond your times. I'm a time traveler
