K "needed" to go to the mall. Three boys were in tow.
Three boys that just don't get the mall.
Nor do the three understand why they are forced to sit at the store's edge and one is forced to rest on a display cable. 
And ultimately to sit in the middle of the mall while the younger son captures moments of the older son.
All while the oldest is getting what she needs - a poster of Edward from Twilight.
