There are actually two incidents and I'm not able to figure out which out of these two is earliest (I mean oldest).

1. I remember I was a toddler, and a faint memory says I knew how to walk, but that day (it was morning) I was crawling under the sofas (God knows why?) and I put my finger in one of the power sockets. And there was a buzzz... my head spun and I the next thing I remember was being thrown away and I remember I was crying a lot before my mother came to pick me up and offered me some sugar from kichen :)

2. This one is a bit clear compared to the previous one, my mom had this sewing machine at home and used to mend some of her clothes by herself. It was my native place, the sewing machine was kept in the veranda, mom wasn't there so fascinated by how it works (I'm guessing, god knows what my teeny tiny brain was thinking at that time). So determined I walked up to it, put my handkerchief under the needle along with my left index finger and rolled the machine pulley... BAM!! within milliseconds the needle had poked my index finger thrice. I remember not crying but staring at my finger before my bua (father's sister) came running and took me to the doctor.

But I remember crying after the tetanus injection :)
