Nicknames

Our little comic has done it again. While waiting for Dad to get some fast food to go, the rest of us were sitting in the food court next to an older couple. The man turned around and was talking to my children and he said to Lily, 'You're cute,' Lily smiles and then he turns to Emma and says, 'and you're so pretty,' Emma also smiles. He then turns to Isaac and says, "And you're a handsome young man." Isaac looks at him with the most serious expression on his face says, 'No... I'm a knuckle-head.'
Kris calls him that little nickname and I guess it stuck. Kris and I both got a good laugh from it.
