The recent deal has no ties to the reason I have placed negative reputation on your profile.
You contacted me just to tell me that I buy items and oversell them. You then claimed that I do such because I'm "a poor f*ck" (your exact words). You then made an attempt to sound smart, when you couldn't even properly word sentences (which I had corrected you on, which must have angered you further [even though I had done nothing to you from the beginning]). And then the final five minutes of that conversation, you just decided to continually call me "a poor f*ck" and a "dumb ass".
So yes, I think of you as a "piece of shit".
