I almost got my thumb cut off as a child
What happened that caused you to almost lose a thumb?
I was playing around with a knife and I did something careless.
I'm glad nothing bad actually happened to you!  I hope you learned not to play around with sharp objects after that!
Yeah, and then I learned to use a knife properly.
Have you had any other close calls with losing a body part? I imagine you might have been scared when it happened or even a bit traumatized.
