“And I regret that we couldn’t have a civil exchange…like adults.”
“Take some valium first. Sell your house, and get over it.”

May I suggest a 4th reason for your list: I get irritated at your posts because you can’t seem to even imagine the possibility that you could be wrong, and you are convinced the only reasons someone could disagree with you are fear, jealousy, or ego. It’s incredibly condescending.

The financial sector has a lot riding on the housing bubble. Do you think it’s impossible for that industry to come up with something clever and/or evil that hadn’t occurred to you?

I say this as a lifetime renter who hopes prices drop like a stone, by the way.
