I know, I don't know how I got it inside my nose too. LOL.
I don't remember the whole thing, because I was just a little girl back then, but what I remember is being taken to the clinic near our place and the doctor inserting some sort of thin tweezers in my nose.
I was watching tv while eating watermelon seeds. A few minutes after my mom left me, she saw a tiny lump on my nose. When my mom took a peek inside, there it is, a watermelon seed. :)
Apparently, I had a cold that time, and my nose was itchy, so I used a watermelon seed-which I was eating-to scratch my nose. I don't know how, but i somehow managed to put it inside my teeny tiny nose.
My parents brought me to the clinic, and voila!, I'm good as new. :)
Given the chance, I wouldn't let anyone else experience this because although funny, it's clearly an act of stupidity. :) LOL.
