I remember taking this picture of me, by a 7year old kid... I remember him pleading to handle my first DSLR back then, and i remember him taking most shots blurred.
The most interesting part of it is that, i didn't bother deleting them, not a single one, i had no idea i would even touch it, until yesterday while having a lonely time in the house, i decided to play around with pictures on my pc, just to fill up the time.
Then i came across this picture and decided to do something about it finally. At least, the little guy's effort wasn't in vain...
Cheers
