No going back

So yesterday I did it. I signed the contract and paid 20%. The sellers turned out to be a really nice couple, and since we'll be neighbours from next summer it felt good. I so look forward to March, when they will start by taking down the trees and get the bulldozer out. After meeting the very unpleasant woman in the registry office (where do they dig up these people?) they invited me for coffee and we had a nice chat, just starting to get to know each other. They suggested that we use the informal "Du", which I understand is a big thing here. Or maybe they just realized that I'm not entirely fluent in German :) Whichever the case, I'm relieved they turned out to be easygoing people. And they paid for coffee...
