messing up at work

hey everyone, so today i did something kinda dumb at work. my boss was trying to get a new system set up and i totally thought i had it figured out but turns out i didnt. i ended up deleting some important files by mistake thinking they were test copies or something. the thing is, i spend so much time making sure everything looks perfect on the surface that i kinda lost sight of actually understanding what was going on behind the scenes. now i have to face my boss and explain it all and i'm just worried about how she's gonna react. oh well, at least it'll be a learning experience right?
