A spider in your bathroom is not necessarily a bad thing.

 I saw a spider hanging around some decorative bottles I have on my bathroom sink.

First instinct is to crush the spider. Then I said to myself, "Self, leave it alone and let it do what spiders do" and my spider did what spiders do! It was a tiny spider, but it did do some nasty...

The spider also got two bees that I swept away

before I took a photo...

No idea where the spider is currently

spinning it's web.
