Spider

Alright so tonight I was walking across the kitchen when I saw Joshua he was screaming, pausing, and then yelling bad at something. I thought it was just adorable, till I let my face come two inches away. Reeling back in fear I screamed.
"Mom there's a spider!"
Dad said, "Johnny go kill the spider."
I'm just standing there in horror. Staring at the black arch of a creation. Obviously it was alarmed and ready to kill.
Johnny finally came into the room right as the spider moved and I ran out screaming. A little later I heard it was killed and went to check on Josh. I turned around about to hug Josh. My arms were opened and I started to get on my knees.
Kate then burst in, "Josh is holding the spider."
Again I jumped back screaming! I looked closer at Josh's hand and saw the black shadow begin to (as it seemed) crawl out of Josh's slowly growing open hand. Being a coward I ran out screaming, again. Later I discovered that after the spider had been killed Josh came up to it, told it it was bad, and poked it. The spider then was for some reason sticky and Josh couldn't get it off till soon after I left.
