Jack had forgotten how sensitive girls could be. Their overreaction to teasing, disliking their pigtails being pulled, and throwing hissy fits when their toys are taken. Thankfully for the most part Fiona was pretty good, usually it was just the two of them, a stronger bond through their father's passing had been forged. As a small child her most annoying factor was following him around, trying to be just like him. He'd act upset, but in secret would smile at the frantic yelling of his name. When they got older she just got strange and obsessed, not with boys, makeup, and the latest celebrity gossip, but instead with ghosts, ufos, and other paranormal crap.
With Annie it was different. A lot different. While she to talked about three headed creatures and haunted mansions, she did like gossip and popularity. Jack could tell Fiona she looked fat in a certain shirt (only joking) and she'd just yell at him for being and jerk, that was it. But Annie? After the comment started to cry like a child would do.
