My house's basement is about one meter and a half high and I often store machinery there. When my kids were small, I didn't want them to play there because it was dangerous. And because it was off limits, as all kids in that situation, they were drawn to it anyway. That basement being hard packed earth is paradise for insects. Say insects, say spiders. In the entrance there was a HUGE spider(for this climate) an inch across. I typically am respectful of life of any form, so I kept it there unharmed.
One day as I was getting in the basement to fetch part of a machine, my son, then 6, who was shadowing me came face to the spider. He froze in terror and said in a weak voice:
"Papa!"
I turned to see him locked in his footstep, facing THE spider.
*Flash*(Gotcha)
I quickly yelled:"Careful...That is the boss of my guardian spiders!"
The first named that popped up was:
"She's Victoria and she's mean. Be careful!"
It took years before he got in there again.
