Look before you leap.
I learned this today. I went on a hike with my friends on the Rivanna River Trail. It was a part that was once a Forestry nursery back in the 1930s and it was beautiful and very interesting.
When we were almost back to car, I noticed a big stretch of gorgeous green grass and so I spontaneously threw off my backpack and laid down on the grass.
But it wasn't as soft as I imagined. In fact, it kind of pricked me. So I sat up and felt around on the grass, trying to figure out why it prickled. I noticed a bug curled up with all its stingy feelers sticking out. With a sigh and my impulsiveness, I picked up my bag and walked back to the car. A friend followed, having thoroughly enjoyed his stint on the grass. I noticed a red mark forming on my wrist. My wrist started to throb and pain shot up my arm. I looked down my arm and realized I had several blotchy marks forming. One of my friends laughed a little, "You contracted leprosy!" The white blotchy marks continued to swell. And then little dark marks appeared in them. We looked it up, realized it was just a centipede bite (or several of them) and that it wasn't dangerous - it would just hurt and swell. So I went home and washed my arm. They say to use cold for swelling and heat for pain. I have both so I'm not sure which one to use or if they would counteract. In any case, I'll live. But I have a good story and a lesson learned.
It was a fun day anyway.
