A couple weeks ago when I picked up Will from daycare, one of his teachers (I guess you'd call them that) asked me:
"Does Will like fishing?"
Of course, he does. The reason she asked was that when the kids were playing outside that day, Will had found a pretty good long stick, and was running around pretending it was a fishing rod - casting it and reeling it in. Since then I've seen him do this on many occasions with other long sticklike things, sometimes getting Duke involved, because it's fun to fish for Duke.
So on Will's birthday when we went to the fruit orchard, Will found a long piece of straw and started doing this - all of us had a good time cheering him as he was pretend-fishing.
