Who Says That?

My son has always been a thinker, thinking things through one step ahead and drawing some unpredictable conclusions.  The following conversation took place last week between my son and his Daddy.

Son: Dad, I really want to go fishing.
Dad: Oh, that does sound like fun.  The bummer though is that it’s not fishing season so we can’t go fishing.
Son: Why is it not fishing season?
Dad: Well, if we fished all the time we would run out of fish to fish.  Instead, we give them a break so they have a chance to have babies and make more fish.
Son:  So then we can destroy the families and eat them?
