there was a situation a while back where i had a link to a hentai games forum in my copy / paste clipboard, and i went to send a friend a link to something else forgetting i'd copied this link and he was just like "hang on a second, why're you sending me this?". luckily though, there's been a long running "joke" of sorts regarding this person and hentai / cartoon porn for various reasons so he shrugged it off as me just trying to annoy him, when infact i had the link for my own personal benefit and had accidentally sent it o.o
as far as stuff on my computer, i stopped downloading things ages ago so there's nothing anyone could get from my computer, but it seems like having downloaded copies of things is more efficient so i might start again, and just leave it in a buried and password protected folder, aha.
