Graham loves hanging out in the yard; helping me pick herbs in the garden; and dumping our compost in the pile (he'd actually like to play in the compost, but we don't allow that sort of thing unless you are a dog).
He picked our first tomato; bit it; decided he didn't like it.
Not 20 minutes later, I found him eating rocks with a smile on his face.
Not sure where he gets his palate from. We enjoyed salmon and fire roasted baby carrots that same night. They tasted nothing like rocks at all.
