My doctor says I shouldnt think at all.

And once a real duper duped my Stormshield (first he gave me a bunch of sojs, a few raven spirals, a 09 Valor and some other stuff) then gave me 3 SS back, granted they were all probably the dupes while he kept the legit one for himself, but no matter cause I traded em all for sojs and bought them back unid after the new patch came out.
This was a long long time ago before I had quit.
Anyway, one time this one guy was telling me if I wanted to dupe something to drop it on the ground while he was on the other side of town, he wanted to "dupe" One of my sojs, so anyway I say "First a test run" so I go out for a couple mins killing monsters until I come to a crappy rare ammy, I remember the stats and drop it and say "Okay show me what ya got" and he says "That sucks you dont wanna dupe that" I told him it was just as a test cause I didnt wanna lose a soj and he replies "No it only works once" so I say "Then I'll get a new char on a new acct and do it to the real one" and he says "okay" somewhat reluctantly...
Ahem, so he starts giving me this BULLSHIT about how there's a complicated menu that comes up when I press ALT + F1 all the way to F12 then the menu comes up and its "very complicated"
Anyway so thats right around when I told him off and he left.
This as well was a long long time ago before I quit d2 for the first time.
