What Makes People Scared And Stuff?

So, I'm sittin' here doin' some thinkin'..............
So I says to myself, Self, what makes people scared and stuff?

Hmmmmmmm............... what makes people scared?

Let's see, I remember one time I visited an old peoples home dressed up like the grim reaper. Yep for some reason those old people, especially the real old ones were pretty scared. I could never figure out why they were so scared.............

Or like if I'm drivin' around and stuff in my fancy 1975 AMC Pacer, and I see a bunch of little kids playin' in someones back yard. I'll lean on the horn, and lock up the brakes so there's a really long horn toot, then screechin' tires and stuff. Man you see alot of really scared lookin' people people come runnin' out their front doors screamin' "Billy!" or "Mary", or stuff like that. Yep, they look really scared. I wonder why?

Or like when I have people around, and they see that I'm feedin' my dog Yabaastad some hot dogs. Well that one I understand - yep a little while after Yabaastad eats hot dogs, you can bet that your eyes will be waterin' and stuff...............

Hmmmmmm..........what else makes people really scared I wonder.........
