<human>: Give me the gist of the text in a nutshell

This is more of a small world story than a fucked up mortal enemy story, but i hope some of them come along too. so i'll start, when i was really, really young (like grade one i think or even before) i went to this after school care as some kids with working parents do. i can't fully remember it so lots of what i'm repeating is what my mother has told me but essentially this kid bit my arm really hard, so hard in fact that it tore the skin enough that i needed stitches. needless to say, i hated that kid after that, but he actually moved away and moved schools and everything pretty shortly after. I had completely forgotten about him until years later i'm starting high school this weedy little guy who was about half the size of every other guy in the year (all boys school) walks into my classroom and i instantly decide that i don't like him (judging by his face i guess??). months pass and i keep feeling like i recognize him from somewhere and the more i get to know him the more i wanted to punch him repeatedly in the face, i got to know him in the sense that he always had something to say no matter what subject or how little he knew about it. but anyway, later that year after our class photo my mum was looking at it and noticed this kid's face/name and told me the story of what happened at the start of my schooling career and how odd she thought it was that we ended up at the same high school just by coincidence. so after that i resolved to hate this person with every atom of my being, i still give him the stink eye if i see him.
<bot>: Kid bit me so hard in preschool i needed stitches, ended up at the same high school by coincidence and i still hate his guts after finishing school.
