Power Washing

So, I just got home from work, and the management is having one side of my apartment building "power washed" today. I knew this was happening; last Friday, we all got notices from the management telling us to move our cars away from the building today for power washing. Said notice did not remind us to shut our windows, but I, of course, did so anyway. The notice did tell us to shut curtains and blinds as the washer guys would be right outside the windows. Well, when I got home, the power wash guys had worked their way down the building and were right in front of my bedroom and office windows. When I got inside, I realized that a lot of water had leaked in, a lot. I went out and told power washer boy that my windows were leaking. And he's all like, "The windows are closed," and I'm like, "Yeah, I know I closed them, but they are leaking from the top," and he's like, "Well, they said there might be some leaking." Now I don't know who "they" are, and the notice I received said nothing about potential leakage. And he's like "OK, well someone can caulk it later," and he procedes to spray more water into my apartment.

Is it just me, or does this seem dumb? I'm opting for dumb.
