I was stung on my forearm by a wasp while I was sweeping the garden. There was a little wasps' nest on an avocado leaf in my garden. It was a house of about four wasps. This kind of bee is known to be bellicose, aggressive warriors. And I accidentally stirred them up when I touched the leaf -- and immediately felt a pain on my forearm. I automatically waved my arm constantly and ran away when I saw some wasps flying out from their nest. It's the first time I was stung by a wasp. Although that feeling was not comfortable at all (It's more painful than getting an injection), I also felt rather excited about that event. Maybe I tried to comfort myself by making a positive feeling. The wasp gifted me a little red hole on my forearm, as if from a shot of injection but using the kind of needle for drawing blood. I recognized some clear liquid like water on the hole. Maybe that was the wasp's poison. I hurriedly ran into my house and washed my forearm under a faucet and then dried it with a towel. Next, I rubbed a little oil on the sting and continued sweeping. However, the pain was not able to prevent me from peeping into the wasps' nest sometimes to watch with curious eyes those who attacked me. Actually, they just attack when they feel they are in danger. The pain was gone after an hour. But the next day, my forearm was a little bit swollen. On the third day after the accident, the swelling was down, but I felt itchy around the sting. Now, everything is almost back to normal. It's quite interesting to observe that process. Although this event was rather interesting, I'm sure I don't want to experience it again. It was lucky for me that there was only one wasp that attacked me, otherwise I could have died with many stings on my body. I should be more careful when working in the garden.
