Why a wastebasket?

I just escorted a spider out of our bathroom wastebasket. Why in the world do you suppose she thought that would be a good place to set up household? I'm sure it wasn't in eager anticipation of my toenail clippings. In fact, she seemed most unimpressed. I hope life is better for her in the jade hedge. At least there will be fewer toenail clippings out there.
