Feedback is left because a "deal" went good or bad, not because your upset. Stick to your guns while selling, or buying. And be firm and fair all the time. And there is nothing wrong with asking the seller questions about the product. If you don't want to politely answer the questions, then don't. I'll bet they'll buy elsewhere though.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
