this is probably a fitting enough first post
when i was much younger, i went by "8-bit ninja" online. it's about as juvenile as it gets -- i liked retro games and shonen anime.
a bit later, i had grown out of it. instead of coming up with something entirely new, i considered just shortening it to "eight", because i realized that if i had a favorite number, that was it. instead, i chose "ocho" (it means eight in spanish) because at the time, i had been studying spanish for 2 years and was actually really enjoying the learning process -- something which doesn't happen very often for me
unfortunately, i stopped consistent study of the language many years ago now and am not yet conversational in it (thanks, covid-era depression), but i hope i can rectify that at some point.
