I don't remember being this bad, but karma is real.
I'm getting the snarky, argumentative, attitude filled replies for everything.
Back in my day it was different as if I got snarky/argumentative I got punishment detail (ex-military father). I still hate gardening to this day.
On a few occasions I pushed my luck and found out that the military also used corporal punishment. After that I learned to get sneaky.
Puberty is such a weird thing. One minute they are mostly happy, caring, energetic little people, then the next they are mostly lazy, uncaring, mouthy, difficult, and downright unpleasant people.
They will learn to be human beings in a few years if you set the right example, but in the meantime you are in for a real rollercoaster ride.
Even harder as a step-Dad. You have my sympathies.
