Fairies in the front yard...

 You know what this is...

It is evidence of fairies. My children spotted these mushrooms in the front yard and asked me where they came from. My answer (which, of course, is the absolute truth) is that since fairies live under mushrooms, we obviously had a small troop of fairies camping out in our front yard.

 Matt and Molly were quite concerned about where the fairies were now. I explained how they don't stay in one place too long and they must have stayed for a night or two and moved on. The kids have been watching for fairies outside ever since.
