I've never been what you would call a hard negotiator. I hate dealing with sales people, and just want most buying experiences to be done as quickly as possible. For major purchases, I do the minimum research necessary to ensure I am not going to get flat out screwed, and am willing to pay more than rock bottom to wrap things up.
Combining this self-identified lack of a 'negotiating gene' with the fear that our house might NEVER sell(despite the fact that it had only been on the market 3 months, over the holidays, at the tail end of one of the worst housing markets my generation will see) and there was ZERO chance I was going to play hard-ass with the offer to buy our house. With them already offering full asking price, the only thing I really could have done was try to talk them down on what they wanted us to cover of their closing prices. But, the was I am looking at it is, I had already convinced myself that I would not have flinched at accepting five or six thousand less than we had been asking...so, why worry about this closing cost thing.
Besides...if I HAD played Mr. Hard Ass, and the deal fell through...it might have been a chance to finally figure out just what the worst thing is my wife could do to me.
