So...tonight the boys are concerned about the number of flies in the house.  Honestly, there were a lot less of them before they left the patio door open for about 30 minutes, but that part isn't important.

They have been all over the house killing flied in what seems to them to be our fly-infested home.  There have been casualties.  I'm told eight flies have not survived.  A green vase was broken.  A hole was created in a t-shirt.

What is going on here?  I can honestly say I have seen no flies.  Could be the expert killing done
OR it could be that there really weren't that many in here to begin with.
