why are they putting sanitizer on their arms?
I can’t understand that too. If your arms are touching something then take a shower.
When I was in high school, I read an autobiography - IIRC, the title was "Manchild In The Promised Land" and the author was Claude Brown. For whatever reason, the part I remember most is his story of being home alone with other kids when he was about 8 or 10 years old, and using Vaseline to fry eggs because he could not find the Crisco.
It sounded believable, especially when I consider the crazy stuff I tried as a kid, so when I see stories like this it's makes sense in a "kids learn some things from experimenting" way. If nothing else, they learned never to do that again!
Because they’re stupid and easily led.
All sanitizer is good for is spreading the germs around. Soap and water and rinsing is much more effective.
