I grew up afraid of lots of things - pick pockets, eye injury, murder, theft, dislike, new places, and many other calamities.
I carry a small card wallet in my front pocket to this day. Why? My parents taught me that there were pick pockets everywhere and that they could steal my wallet from my back pocket without me even knowing it. While I had a normal-sized wallet I would move it to my front pocket of I went anywhere new. I felt like a dork. So I eventually got a business card wallet and put my driver's license and debit card in it. I would keep that wallet in my right front pocket and my cash in my left front pocket.
I loved to mow when I was a teenager. We had a long driveway and I would get out there in the middle of the day to get the most tan from the sun; I would almost always come in sun burnt. Mom said that mowers throw stuff and something fly up and poke me in the eye so I should wear sun glasses. So after mowing I would look like a reverse raccoon. I don't do that anymore. Still have both eyes.
We watched the 6 o'clock news every night when I was growing up. That way Mom and Dad could be informed and know what was going on. They would tsk at the stories of theft.
