It's a close draw for me, the first situation is when, as a child *5 or 6 years old I forget which* I was attacked by a huge, blind, St. Bernard. The dog's head was nearly the size of my entire body at the time and there were a few seconds where I was literally inside the dogs mouth, before my dad kicked it in the ribs. After that it took years for me to overcome my fear of large dogs, I wouldn't go near them at all until I was nearly 18 years old.
The second situation was many years later, I was a sophomore in highschool and my older brother was taking an automotive course at the Vo-Tech institute that was affiliated with our school. There was an accident and my brother's hand was cut down to the bone *to this day he has a large scar on that hand*. But that's not the rumor that got back to the school. I heard everything from his hand was cut off to his whole arm to he bled to death on the way to the hospital. I was terrified and I didn't hear otherwise until after I got home from school that day.
