Pets or Pests?

Alex brought home a couple of "friends" from school today: a fly and a spider in bug containers. We also found an ant on the sidewalk as we were leaving school, which he wanted to catch and put into one of the containers. While we were trying to do that, we discovered that the lid came off of the spider's container in Alex's backpack so I had to catch the spider and put it back in. I'm guessing that by now the ant has become dinner for the spider.

I'm not sure how I feel about this new phase of boyhood!

The spider is in the top container, and
the fly is in the bottom.
