窓を開けれました

So at the end of the hall outside of where I work there are some windows, they have a nice view. And there's a little red button on the windowsill. Typically this button is covered by a plastic plate but the one here had falling out. I accidentally pressed the button while fidgeting and lo and behold, the window open. It was unfortunate that the one person fluent in Japanese ABANDONED me after it opened. He just grabbed his banana and split (oh yes, I said it). One angry Lumine (they own the building) woman and a good humored security guard later, the window was closed. It was nice of them to put an open button on there but no close button...
