I have had lots of interesting encounters with spiders.
I was working on a trail bike I had one night in an enclosed patio area (quite small) when I saw a palm sized Huntsman casually strolling toward me on the ground. I got up and thought if I stamp my foot in front of it, it will run away. To my amazement, it only move back about it’s own body length, turned back to face me, and then charged at me along the ground. It got to within about half a metre of my foot before I became the one being chased out of the room.
A few years ago I was under one of my (many at the time) project cars doing some work when I could feel something biting my leg. Having lots of ants around I thought that’s what it was. When I got out from under the car my leg was feeling a little sore so I pulled up my tracky pants leg to reveal a line of bite marks from my ankle to my knee, and much worse than what an ant might do. Upon further investigation I found the remains of a red back in my pants. It was really sore and swollen for a week or more and the first day or two, I was not feeling good at all.
