it always scares me

when i plug something into an outlet, and that fleshy part of my finger comes into contact with the metal right as the prongs go into the socket. it scares me. perhaps because i've touched a wire before and felt the electricity race through my arm. it hurts. and im afraid that one of these times it will keep going. it wont be just that thrill of the energy coursing through my body...no, it will hurt...for so long and then stop. but it wont stop because my hand wont have left the metal. it wont stop, but i wont feel it anymore. i wont feel anything anymore.
