Input: Text: not a big fuck up, but it was still fuckin' dumb. i was packing up something to ship to someone over /r/hardwareswap. i'm almost done packing the whole thing, just taping the last little bit, and i notice that the scissors have some tape residue on them. normally i would ignore that sort of thing, but it was making the scissors kind of stick together when opening them so i decided to try to rub it off. yeah, you can see where this one is going. so, i cut myself, put a band-aid on, and all is well and good, right? wrong. i head back upstairs to finish the job, and somehow i completely forget about getting a cut on my left thumb not five minutes ago. yep. other thumb is cut too and i'm left feeling like a dumbass.

TIFU by trying to rub tape residue off of a pair of scissors. Twice.
