When blackberries "grow up"...

Along the one-lane road up to our house there are dozens of blackberry bushes that they boys have been waiting (im)patiently to produce berries.  We have to talk about them every time we walk by.  Recently, Jon decided to impress Jake and I with his knowledge of blackberries and informed us "See those little green ones? When they grow up. they'll be black. Then I can eat 'em!"
