Everyone loves their own children more than others. They tell you how beautiful they are & how proud they are as a parent.
When you meet them they are a funny looking thing with a limp hand shake.
Seems to me that buying guns is the same.
Eye of the beholder & all that.
So a deal is near always (unless a red haired step child) that the seller takes less than his optimum & the buyer pays his near maximum.
A negotiated position of compromise that your seller has not the honour to uphold when sellers remorse kicked in. Poor man. It may be best for him to keep the gun.
