I would like to know the meaning of (1) and (2).
1. stripping her gears.
2. Her trial starts next month.

A teacher was helping one of her young students put his boots on.
He asked for help and she could see why. With her pulling and him pushing, they finally succeeded and she had by now worked up a sweat. She almost whimpered when the little boy said, "They're on the wrong feet."
She looked and, sure enough, they were. It wasn't any easier pulling the boots off, and then she had to wrestle the stubborn boots on again.
Just as she finished lacing them he announced, "These aren't my boots." She bit her tongue to keep from screaming, "Why didn't you say so?"
Once again she struggled to pull off the ill-fitting boots. He then calmly added, "They're my brother's boots. My mom made me wear them." She began to realize how close she was to stripping her gears as she struggled with the boots yet again.
When they were finally laced, she said, "Now, where are your mittens?"
"I stuffed them in the toes of my boots," he said.
Her trial starts next month.
Hi,

I would like to know the meaning of (1) and (2).
1. stripping her gears.
2. Her trial starts next month.

A teacher was helping one of her young students put his boots on.
He asked for help and she could see why. With her pulling and him pushing, they finally succeeded and she had by now worked up a sweat. She almost whimpered when the little boy said, "They're on the wrong feet."
She looked and, sure enough, they were. It wasn't any easier pulling the boots off, and then she had to wrestle the stubborn boots on again.
Just as she finished lacing them he announced, "These aren't my boots." She bit her tongue to keep from screaming, "Why didn't you say so?"
Once again she struggled to pull off the ill-fitting boots. He then calmly added, "They're my brother's boots. My mom made me wear them." She began to realize how close she was to stripping her gears She went crazy. Think what happens to the gears of a car if you are going forward fast and suddenly put it in reverse gear. You will 'strip the gears'. That's what happened to her brain, figuratively speaking.

as she struggled with the boots yet again.
When they were finally laced, she said, "Now, where are your mittens?"
"I stuffed them in the toes of my boots," he said.
Her trial starts next month. The suggestion is that she kiilled the annoying child, and is now to go on trial for the crime.

It's meant as a funny story. Nobody really got killed. Emotion: big smile

"Her trial starts next month" suggests to me that she did something following the revelation about the mittens that was actionable in a court of law.

"Stripping her gears" in this sort of situation is a bit uncommon in my experience.

It's an auto racing metaphor, but it can also apply when someone inexperienced makes a false step and temporarily loses control.

In the old days, all gearshifts were manual (stick shifts/manual transmissions), and it often took a newbie a bit of practice to catch on. A failed attempt could result in a terrible ratcheting, or grinding sound. Experienced drivers would holler, "Hey! grind me a pound!" (of hamburger) We postulate that the noise is so terrible that the driver must be "stripping the teeth off the gears." ("Stripping the gears" = "grinding the gears.") When you do this, you temporarily lose your means of propelling the car forward.

If a race driver "missed a shift," it could often cost him the race.

The point to the story is that on the next-to-last attempt, she ALMOST lost her cool.

We're left to draw the conclusion that on the LAST attempt, she actually DID lose it.

Edit. I've never personally known of a case where the teeth were actually stripped off, but I suppose if as Clive suggests, you rammed the gearshift into reverse at full speed, you could accomplish it.
