Most people aren't talking about how they're going to calmly consider the situation and then hit the person. They're referring to the fact that by the time they notice, said individual is going to be too close for a spider that size to get anything other than a fight or flight reaction.
Buuut yes, don't go slapping things on people or something, guys. It does tend to cause more issues. If you absolutely have to hit, do more of a swat away rather than a slap into.
I was thinking that! When I was a kid I had a mole on my neck that looked similar in size and color to a tick. At least once a year someone would try to "catch it"
Luckily more often it was serious looks and warning there was a tick on me.
In fairness, I was in the woods a lot and had to check for ticks on the regular.
But yeah, my grandma for sure would have whacked me upside the head if she saw that spider earring.
My immediate thought was that someone is definitely going to scream and smack him on the side of the head the first time he wears that out somewhere lol
