While playing their new best Christmas present ever -- a Lego StarWars computer game (incorporating three of their all-time favorite diversions) -- Miriam and Jacob were both playing an allegedly cooperative episode. Jacob was enjoying making his character jump around, doing Jedi acrobatics with his lightsaber. Miriam, however, was concentrating on the goal of this particular scene (defeating a particular bad guy, or discovering some hidden secret or whatever). Jacob's antics were not helping. Thus, she scolded, in her best semi-bullying big sister voice: "Jacob! Stop having fun!"
We are taking this as a sign that our kids may be too competitive, or that Christmas vacation needs to be over SOON. Or both.
