Henry, my Henry

Henry is chasing Callie around with vacuum cleaner attachments, pointing them at her and screaming "ha!!" She, in turn, is sobbing (why? nobody knows, since he isn't hitting her with them, touching her in any way, and/or even allowing flecks to dust from the vacuum cleaner's attachments (which could either prove I'm an immaculate housekeeper - I even clean my vacuum attachments!! - or it proves I've never used the damned things. You choose.) to circulate in her vicinity.
I think he's trying his hand at magic tricks: Henry is simply trying to make his bossy big sister disappear. Now if Henry would like to make ME disappear, that would be fine.
