Sharp Lives

I hear things weirdly. I often interpret things differently than people mean. Like, just an hour ago my mom said "Little girls shouldn't handle knives!!!"
And, of course, I thought she said "Little girls shouldn't handle lives!!!"
Which really confused me.
I replied, "Ummm... Lives? What's so bad about a life??"
And she said, "No... Knives. The sharp, pointy things? You cut stuff with them?"
"Oh. Yes. Okay." I said.

Then a little while later, she said "Don't touch the sharp knives!!!"
And then my older sister, who had been listening the first time, said "No!!! Sharp lives!!!"

And then LATER later, my older sister and I were pointing at each other and then she grabbed a Kleenex box to throw at me (my influence, I used to do throw Kleenex boxes all the time) and I said "Oh yeah, well I've got a SHARP LIFE!!!!"
