16 months. It's that age where kids have just begun to know what makes you tick. And Jesse knows.
"If I cry like this, maybe they'll let me flick that light switch a couple of times. Ah yes, it works. Suckers!!! Maybe if I cry some more, they'll let me fire up the gas stove."
And pretty soon, your kid is operating heavy machinery.
Fortunately for us, Jesse is a pretty lousy actor. You can actually see right through his fakery. He'd pull his face into twisted, convoluted expression of sorrow and let out the most fake-ish cry. For effect he might even crouch over some low furniture, striking a pose of tragic melancholy, resting his brow upon his forearm. Somedays the little monkey would even struggle to generate a crocodile tear or two. And somedays, he'd actually succeed.
How do kids know exactly what to do to get their own way? It boggles the mind. Do they learn this along the way? Or did the Art of Manipulation come with their original programming? This is a serious bug in the software.
For parents, the only recourse is a system re-boot. Though a boot to the butt is probably just as effective.
