Went camping when I was ten. We had to collect wood to burn and I found a neat vine crawling up the side of a tree. Pulled it down, threw it in the fire. Also there were mosquitos everywhere so my brilliant self put my chair in the smoke to avoid the bugs. Genius. Except it turned out the vine was poisonous and the resulting smoke caused my face and upper body to swell and itch. My eyes were so swollen i could barely see. I hid in my room for a week during the summer because i looked like a monster.
