Let's talk about the time I accidentally poisoned my sister and I. 
 
When I was a small child I liked eating salt out of the packet. I don't have an explanation for why I did this. On one occassion, I opened a packet and shared it with my sister. It was not a red flag to us that the "salt" was round, and neither of us were strong readers yet so we weren't able to adhere to the obvious warnings. 
Our parents had realized what we did and called poison control who had us drink a lot of water. No harm done.
