My psychic powers tell me you're a lowballer.
I sense (psychically) that you are the hyper-sensitive type, far too emotionally invested in a mere business transaction.
That was a joke but read on mein freund.
BTW - what is a low ball offer? Anything less than you happen to like? What's the name for people selling used goods and wanting full, new good pricing? I'll tell you it is...wait for it..."seller" and it doesn't offend me because I will offer what I think it is worth to me considering market conditions. And if the buyer wants more he could either become offended that someone would dare think to pay less than he is asking or propose that the buyer needs to make a higher offer - or even a much higher offer.
