I once read a story where the hero has a terrible speech impediment. One of his first tasks is to confront a witch. He goes into the swamp and finds her slime covered cavern. She tells him that she is going to test his bravery. He can turn around or submit to the test. He says that he has to go forward.

Is he willing to give up some part of himself, something that defines him and makes him who he is? Fearing he'll lose his face or his memory, he agrees.

She steals his speech impediment.

I can guess how she stole his speech impediment.

I had a crippling stammer well into my 20s until one fateful night after a few drinks with a young witch....

Let's just say confidence is the cure for a lot of things.

And then, since she had a speech impediment, she could no longer handle the verbal component of the spell to put it back.

No need.

I endure because my success infuriates my enemies.

Haha. That's basically the plot to Sir Terry Pratchett's Wyrd Sisters

Cute idea. But in the story she doesn't get the impediment. Sorry

The best relationship I've ever had with my mother is no relationship.

No wonder they look like this, with all the fumes around them all the time.

I misread fumes as furries and agreed. They got i them thamgs thamgin

I wish. My stutter shows up whenever I don't know the right word. Aphasia is a side effect of like half of my drugs
