One day, while walking along a jagged path, a small fountain in the middle of no-where was gushing with engergy and life. I walked over too it, and it disappeared, and then reappearing, a ugly old troll.

Frightened, I ran away, but he kept showing up right in front of me. "Go away you vile creature!" I screamed into the woods, as if it were going to listen too me. As it chuckled with evil, it slowly said, "I have a riddle for you... If you answer my riddle correctly, you may go. If you answer it wrong, your life filled with woe."
"Why are you ryming your words...? Isn't it the 21st century...?" I asked sarcastically.
"SHUT UP! and answer me riddle! What walks on four legs in the morning, two legs in the afternoon, and three legs in the evening?"
I wondered to myself, in disbelief, for i have not heard a riddle like this. Hours went by, and i jumped up and said, "Man Kind! Man Kind is the answer to your riddle! you crawl when your young, (morning), your walk in your prime, (afternoon), and you use two legs and a cane when your old (evening)!"
"How can this be?! this can not be! Be gone, young adult of Forney, get out of here!" The troll vanished, and I laughed. I just wanted to go for a walk, but this makes for a good story.
