You Know What That's a Sign Of?

Background information to this story: My children are often little hoarders like their crafty creative-brained mama.  A couple weeks ago we went to the playground near Josie's school where they collected an ungodly amount of small pinecones and acorns which we put into two shoeboxes(without lids) in the Gray Goose.  Main reason was to appease them and get them into the car and stop the whining about leaving the playground.  And of course based on how often I clean out the car, they have remained there.  Except that last night after Josie's first time cheering on the pom pom squad for the little league football team, as I attempted to get Sawyer out of the car, he knocked one of the shoeboxes out and pinecones and acorns spilled out onto the driveway next to his door.  In the dark I gathered mostly just pinecones back into the box and put it back in the car.
Which brings us to this morning.  Jimmy has been sick the past couple days with a cough/cold/fever thing which seems to now be spreading through the minions.  Thus we have a more relaxing Saturday morning than our usual hustle to make it to Jimmy's flag football games.  A.J. headed out to grab us some Dunkin Donuts.  About a minute after he shut the door, he came back in and in a serious tone asked me to come out front with him.  I hesitated as I was still in PJs and no bra and he says to just grab Bart and hold him in front of me which I do.  I step out on the porch and he goes over near my car and points down at some stuff on the ground that looks like little brown balls or something.  He says: "Look at this!  You know what that's a sign of?"  I am squinting to see since I have my glasses on which need updating.  I take a random guess since we do live in a very "country" neighborhood with a lot of wild life.  "I don't know- deer." Thinking in my head that it's deer poop.  Then A.J. starts getting a bit more riled up and says:"No, those are nuts!  It's a sign of squirrels!  You probably have a squirrel living in your car!!"  Then it dawns on me about the shoebox spilling last night and I start cracking up and yell back to him: "Actually, it's a sign that Sawyer spilled the shoebox full of acorns and pinecones that your oldest two collected at the park the other week!"
The best part is I am pretty sure that the chain smokers who always walk their two dogs past our house twice a day while smoking witnessed this whole thing...
