This really hurts a bit. It's like I've been electric grounded by plugging appliances in the wall socket for like hundred times. Everytime I plug a wire to wall sockets I always feel being nervous. I think I'm traumatized by the surges of low electric bolts from the wires. I already told this to my mom, she instructed me to keep my hands dry or use a cloth to grab the wire before plugging it in the wall sockets. That works most of time. I just don't understand a while ago why I've been grounded again. My right hand is kinda wet because I just drink cold water from the fridge so I had to use my left hand which is dry but to my shocked I'm still hit by the electric ground. Well, lesson learned.
