Nobody was "cheering" that I saw. The person above was simply pointing out that there's nothing to feel bad about. My house also went up in theoretical value (by a lot more than 10%, too). Why on God's green earth should I feel guilty over something I had no control over whatever? I am neither happy (since I haven't realized any gains and so it would be premature to celebrate), nor do I feel bad (since I had no responsibility in causing the current state of the housing market).
