No Mutants Allowed

I found it trying to climb the bathroom door, but I moved it to the window ledge, where I've seen other spiders manage to make a living. No idea what they actually catch, since I never see any flies there, but I've had one or two spiders live through the winter. Apparently, they do get something now and then

It moved quickly away though, from the window. At one point it wanted to fight me, but then it scurried off and up, and the next day it seemed to be scoping the situation at ceiling level

This morning it had established itself in another corner, and was building the base strings, for the rest of the web. It seems very acutely aware of my coming and going into the bathroom, maybe my thunderous vibrations as well as the light going on and off

I'm wishing it well, next few days will be positive degrees, so maybe theres an elevated chance something tiny will get caught in its web, even though I - like I said - have no idea what they might be catching. Even in summer there's very few insects coming in here
