Write a story that seems normal on first sight , except for one small detail that makes it extremely creepy on a more careful reading [ WP ]

I was running late, and I had to drop off my children at the school and then daycare on the way. Carol had to pick this week of all weeks to volunteer to work over. Fucking great. 
 
 The house was a scene of chaos with Aiden screaming and trying to undress himself as I had the diaper bag slung over one shoulder, his backpack over the other, a bagel pinched between my teeth, and a towel to mop the milk off of him as I got him into the passenger's side and the baby secured in the car seat. Aiden was screaming, snot was flying everywhere, and his incessant kicking was leaving muddy shoe prints on the dashboard. 
 
 I love Aiden, but he is totally unmanageable some days. There are days I honestly wish I was n't a parent. I mean, I would n't trade my children for anything, but it would be nice to have a break from the screaming and the tantrums. When I walked Aiden to his class, I was relieved to have the door shut behind me. The rest of my work day was easy without the extra noise.
