Hot Peppers and My Mouth do not mix

I planted some cute pepper plants in my backyard planters this summer, alongside some tomato plants. The peppers weren't really productive--every now and then I'd go out and cut off a nice green pepper about half the size of my fist.

They were sweet, bland, but added some nice color to my Saturday egg dishes.

On Wednesday of this week I took a cute little pepper with me to work. It had begun to redden, and looked happy on my desk next to some fresh tomatoes.

Late into the afternoon I was craving potatoe chips. I reached for my pepper and bit off the tip. Nice, sweet, crispy. I took a bigger bite, much the same. The third bite brought me into the red part.

SWEET FIRES OF HELL!

My mouth burnt. Tears streamed down my cheeks. I couldn't move. I finally managed to spit out the mouthful after crying out. My eyes turned red, instantly.

I ran a block for milk.

In heels and a suit.

I RAN.

What happened to my sweet peppers?
