I was sitting on a chair in the middle of a messy room during daytime. A friend was also here. After a while, a large yellowish-brown spider started to crawl down from my chair leg. I was shocked and stayed still as I watched it get back onto the floor. A few seconds later, the spider tried to crawl back up the leg. I instantly got up from the chair. I said to my friend how I’m usually against hurting spiders but this time I felt rather threatened.
