I let things alone. I usually put them outside, but I don’t mind sharing my living space with my fellow creatures if I see some reason as to why they would be better off in the house.
This summer I had a spider in my room, right above the window. Some time near the end of June I saw a fly caught in the web. I watched it struggling for a while, in a purely observational way, then left the room, forgetting about it. A few hours later I reentered the room and saw the same fly still struggling, and really struggling. The poor little guy was thrashing all over the place, making a pitiful buzzing with his wings, which were caught in the web. I felt sorry for him. His will to live was so strong that he had been struggling there for hours, and if I wanted to I could save his life.
But I would be denying the spider the dinner it had worked hard for and was now expecting. The spider had put energy into building the web, and had waited for however long it had waited for a fly to be caught, and for all I knew, the spider could have been waiting for weeks for this fly.
My sympathy for the underdog won out. I figured that if I couldn’t untangle the fly I would place him back where I found him. I took him out of the web, and managed to remove all of the sticky web from his wings. When I was finished I released him outside. He flew away and I felt satisfied.
(I was messing with evolution here. This fly would not have lived in a purely “Survival of the Fittest” world. It was unnatural for him to have escaped. He probably went on to breed more flies who will fly into spider webs. But there’s nothing unorthodox about helping another human being. Neither is there anything wrong with helping a member of a different species.)
After a while I began to feel sorry for the spider as well. While removing the fly from the web I had damaged the web. The spider had missed out on a meal because of me. It began eating away at me until I decided to make up for it. I caught a fly that was buzzing around my lamp, killed it quickly, so it wouldn’t suffer for hours the way the first fly would have had I not saved him, and placed it in the web. I felt terrible that night. I have since made it my rule not to interfere with nature.
As the summer went on I continued keeping my eye on the spider. I grew rather fond of her. I watched her while she mended her web, and if I happened to find a dead fly on a window sill I would place it in the web.
My mother didn’t approve of the spider. She wanted me to get rid of it. She told me it would be fine outside; I retorted that it would be fine exactly where it was. My window was prime spider real estate. My window is always open slightly during the summer to allow for ventilation, and so there were always bugs flying in and out, some inevitably getting caught in the web. And being inside, the web was never destroyed by rain. I wouldn’t have minded so much, except that there was a ball of eggs in the upper corner of the web, which would die if I removed the mother spider. I put up a good fight for her, and my mother conceded. The spider wasn’t bothering anyone one bit, and in fact, I was enjoying watching her.
Then I went away for about a week, and when I came home the web was gone and the room smelled of Raid. So be it.
