I don't think the poster is 10 yo, "in year 6" & "in year 10" is standard lingo for students in primary & secondary school in at least Australia. If, for example, a child started school at the age of 6 (year 1) in "year 6" that would make the child 12 yo and in "year 10" it would make them 16 yo. So, my guess is that the poster is well over 13 yo.
With regards to the markings, I've often noticed similar "stitch-like" markings after a scratch with a sharp 'instrument', chances are that you only got scratched and could not pin-point or remember how. And now, some years later, perhaps for the want of a special feeling, you are attempting to associate it with something special, imho.
